# If you have got any problems configuring this file, take a look at
# /usr/share/doc/packages/SuSEfirewall2/EXAMPLES for an example.
#
#
# All types have to set enable SuSEfirewall2 in the runlevel editor
#
# If you are a end-user who is NOT connected to two networks (read: you have
# got a single user system and are using a dialup to the internet) you just
# have to configure (all other settings are OK): 2) and maybe 9).
#
# If this server is a firewall, which should act like a proxy (no direct
# routing between both networks), or you are an end-user connected to the
# internet and to an internal network, you have to setup your proxys and
# reconfigure (all other settings are OK): 2), 3), 9) and maybe 7), 11), 14)
#
# If this server is a firewall, and should do routing/masquerading between
# the untrusted and the trusted network, you have to reconfigure (all other

# 14), 20)
#
# If you want to run a DMZ in either of the above three standard setups, you
# just have to configure *additionally* 4), 9), 12), 13), 17), 19).
#
# If you know what you are doing, you may also change
, 11), 15), 16)
# and the expert options 19), 20), 21), 22) and 23) at the far end, but you
# should NOT.
#
# If you use diald or ISDN autodialing, you might want to set 17).
#
# To get programs like traceroutes to your firewall to work is a bit tricky,
# you have to set the following options to "yes" : 11 (UDP only), 18 and 19.
#
# Please note that if you use service names, that they exist in /etc/services.
# There is no service "dns", it's called "domain"; email is called "smtp" etc.
#
# *Any* routing between interfaces except masquerading requires to set FW_ROUTE
# to "yes" and use FW_FORWARD or FW_ALLOW_CLASS_ROUTING !
#
# If you just want to do masquerading without filtering, ignore this script
# and run this line (exchange "ippp0" "ppp0" if you use a modem, not isdn):
# iptables -A POSTROUTING -t nat -j MASQUERADE -o ippp0
# echo 1 > /proc/sys/net/ipv4/ip_forward
# and additionally the following lines to get at least a minimum of security:
# iptables -A INPUT -j DROP -m state --state NEW,INVALID -i ippp0
# iptables -A FORWARD -j DROP -m state --state NEW,INVALID -i ippp0

## Type: yesno
## Default: no
## ServiceRestart: SuSEfirewall2_setup
#
# 1.)
# Should the Firewall run in quickmode?
#
# "Quickmode" means that only the interfaces pointing to external
# networks are secured, and no other. all interfaces not in the list
# of FW_DEV_EXT are allowed full network access! Additionally,
# masquerading is automatically activated for FW_MASQ_DEV devices.
# and last but not least: all incoming connection via external
# interfaces are REJECTED. You will only need to configure 2.) and
# FW_MASQ_DEV in 6.) Optionally, you may add entries to section 9a.)
#
# defaults to "no" if not set
#
FW_QUICKMODE="no"
## Type: string
## Default: any
#
# 2.)
# Which are the interfaces that point to the internet/untrusted
# networks?
#
# Enter all untrusted network devices here
#
# Format: space separated list of interface or configuration names
#
# The special keyword "auto" means to use the device of the default
# route. "auto" cannot be mixed with other interface names.
#
# The special keyword "any" means that packets arriving on interfaces not
# explicitly configured as int, ext or dmz will be considered external. Note:
# this setting only works for packets destined for the local machine. If you
# want forwarding or masquerading you still have to add the external interfaces
# individually. "any" can be mixed with other interface names.
#
# Examples: "eth-id-00:e0:4c:9f:61:9a", "ippp0 ippp1", "auto", "any ppp0"
#
# Note: alias interfaces (like eth0:1) are ignored
#
FW_DEV_EXT="eth-id-00:0b:6a:61:0c:9e"
## Type: string
#
# 3.)
# Which are the interfaces that point to the internal network?
#
# Enter all trusted network interfaces here. If you are not
# connected to a trusted network (e.g. you have just a dialup) leave
# this empty.
#
# Format: space separated list of interface or configuration names
#
# Examples: "eth-id-00:e0:4c:9f:61:9a", "tr0", "eth0 eth1"
#
FW_DEV_INT=""
## Type: string
#
# 4.)
# Which are the interfaces that point to the dmz or dialup network?
#
# Enter all the network devices here which point to the dmz/dialups.
# A "dmz" is a special, seperated network, which is only connected
# to the firewall, and should be reachable from the internet to
# provide services, e.g. WWW, Mail, etc. and hence is at risk from
# attacks. See /usr/share/doc/packages/SuSEfirewall2/EXAMPLES for an
# example.
#
# Note: You have to configure FW_FORWARD to define the services
# which should be available to the internet and set FW_ROUTE to yes.
#
# Format: space separated list of interface or configuration names
#
# Examples: "eth-id-00:e0:4c:9f:61:9a", "tr0", "eth0 eth1"
#
FW_DEV_DMZ=""
## Type: yesno
## Default: no
#
# 5.)
# Should routing between the internet, dmz and internal network be
# activated?
#
# Set this to "yes" if you either want to masquerade internal
# machines or allow access to the dmz (or internal machines, but
# this is not a good idea).
#
# This option overrides IP_FORWARD from
# /etc/sysconfig/network/options
#
# Setting this option one alone doesn't do anything. Either activate
# masquerading with FW_MASQUERADE below if you want to masquerade
# your internal network to the internet, or configure FW_FORWARD to
# define what is allowed to be forwarded. You also need to define
# internal or dmz interfaces in FW_DEV_INT or FW_DEV_DMZ.
#
# defaults to "no" if not set
#
FW_ROUTE="no"
## Type: yesno
## Default: no
#
# 6.)
# Do you want to masquerade internal networks to the outside?
#
# Requires: FW_DEV_INT or FW_DEV_DMZ, FW_ROUTE, FW_MASQ_DEV
#
# "Masquerading" means that all your internal machines which use
# services on the internet seem to come from your firewall. Please
# note that it is more secure to communicate via proxies to the
# internet than to use masquerading.
#
# This option is required for FW_MASQ_NETS and FW_FORWARD_MASQ.
#
# defaults to "no" if not set
#
FW_MASQUERADE="no"
## Type: string
## Default: $FW_DEV_EXT
#
# 6a.)
# You must also define on which interfaces to masquerade on. Those
# are usually the same as the external interfaces. Most users can
# leave the default.
#
# Examples: "ippp0", "$FW_DEV_EXT"
#
FW_MASQ_DEV="$FW_DEV_EXT"
## Type: string
## Default: 0/0

[,,[,port[:port]]
#
# If the protocol is icmp then port is interpreted as icmp type
#
# Examples: - "0/0" unrestricted access to the internet
# - "10.0.0.0/8" allows the whole 10.0.0.0 network with
# unrestricted access.
# - "10.0.1.0/24,0/0,tcp,80 10.0.1.0/24,0/0,tcp,21" allows
# the 10.0.1.0 network to use www/ftp to the internet. -
# - "10.0.1.0/24,0/0,tcp,1024:65535 10.0.2.0/24" the
# 10.0.1.0/24 network is allowed to access unprivileged
# ports whereas 10.0.2.0/24 is granted unrestricted
# access.
#
FW_MASQ_NETS=""
## Type: yesno
## Default: no
#
# 7.)
# Do you want to protect the firewall from the internal network?
# Requires: FW_DEV_INT
#
# If you set this to "yes", internal machines may only access services on
# the firewall you explicitly allow. They will be also affected from the
# FW_AUTOPROTECT_SERVICES option. If you set this to "no", any
# internal user can connect (and attack) any service on the
# firewall.
#
# defaults to "yes" if not set
#
FW_PROTECT_FROM_INTERNAL="no"
## Type: yesno
## Default: no
#
# 8.)
# Do you want to create explicit drop rules for all running network
# services on the firewall?
#
# If set to "yes", all network access to services TCP and UDP on this machine
# will be explicitely prevented (except to those which you
# explicitly allow, see below: FW_SERVICES_{EXT,DMZ,INT}_{TCP,UDP})
#
# defaults to "yes" if not set
#
FW_AUTOPROTECT_SERVICES="no"
## Type: string
#
# 9.)
# Which TCP services _on the firewall_ should be accessible from
# untrusted networks?
#
# Enter all ports or known portnames below, seperated by a space.
# TCP services (e.g. SMTP, WWW) must be set in FW_SERVICES_*_TCP, and

#
# Enter all ports or known portnames below, seperated by a space.
# TCP services (e.g. SMTP, WWW) must be set in FW_SERVICES_QUICK_TCP, and

# Which services should be accessible from 'trusted' hosts or nets?
#
# Define trusted hosts or networks (doesn't matter whether they are internal or
# external) and the services (tcp,udp,icmp) they are allowed to use. This can
# be used instead of FW_SERVICES_* for further access restriction. Please note

#
# With this option you may allow access to e.g. your mailserver. The

#
# Examples: - "1.1.1.1,2.2.2.2" allow the host 1.1.1.1 to access any
# service on the host 2.2.2.2
# - "3.3.3.3/16,4.4.4.4/24" allow the network 3.3.3.3/16

# - "200.200.200.0/24,10.0.0.10,tcp,80,81,202.202.202.202"
# the network 200.200.200.0/24 trying to access the

# If you do not want to allow them however ignore the annoying log entries,
# set FW_IGNORE_FW_BROADCAST to yes.
#
# Format: "yes" or "no", any combination of "int", "ext" and "dmz" and/or list
# of udp ports
#
# Example: "int 631"
#
# set defaults to "no" if not set

# Allow same class routing per default?
# REQUIRES: FW_ROUTE
#
# Do you want to allow routing between interfaces of the same class
# (e.g. between all internet interfaces, or all internal network interfaces)
# be default (so without the need setting up FW_FORWARD definitions)?
#
# Choice: "yes" or "no", if not set defaults to "no"

# Do you want to REJECT packets instead of DROPing?
#
# DROPing (which is the default) will make portscans and attacks much
# slower, as no replies to the packets will be sent. REJECTing means, that
# for every illegal packet, a connection reject packet is sent to the
# sender.

# Choice: "yes" or "no", if not set defaults to "no"

# Tuning your upstream a little bit via HTB (Hierarchical Token Bucket)
# for more information about HTB see http://www.lartc.org
#
# If your download collapses while you have a parallel upload,
# this parameter might be an option for you. It manages your
# upload stream and reserves bandwidth for special packets like
# TCP ACK packets or interactive SSH.
# It's a list of devices and maximum bandwidth in kbit.
# For example, the german TDSL account, provides 128kbit/s upstream
# and 768kbit/s downstream. We can only tune the upstream.
#
# Example:
# If you want to tune a 128kbit/s upstream DSL device like german TDSL set
# the following values:
# FW_HTB_TUNE_DEV="ppp0,125"
# where ppp0 is your pppoe device and 125 stands for 125kbit/s upstream
#
# you might wonder why 125kbit/s and not 128kbit/s. Well practically you'll
# get a better performance if you keep the value a few percent under your
# real maximum upload bandwidth, to prevent the DSL modem from queuing traffic in
# it's own buffers because queing is done by us now.
# So for a 256kbit upstream
# FW_HTB_TUNE_DEV="ppp0,250"
# might be a better value than "ppp0,256". There is no perfect value for a
# special kind of modem. The perfect value depends on what kind of traffic you
# have on your line but 5% under your maximum upstream might be a good start.
# Everthing else is special fine tuning.
# If you want to know more about the technical background,
# http://tldp.org/HOWTO/ADSL-Bandwidth-Management-HOWTO/
# is a good start

# What to do with IPv6 Packets?
#
# ip6tables is currently not stateful so it's not possible to implement the
# same features as for IPv4. We currently offer three choices:
#
# - no: do not set any IPv6 rules at all. Your Host will allow any IPv6
# traffic unless you setup your own rules.
#
# - drop: drop all IPv6 packets. This is the default.
#
# - reject: reject all IPv6 packets
#
# Disallowing IPv6 packets may lead to long timeouts when connecting to IPv6
# Adresses. See FW_IPv6_REJECT_OUTGOING to avoid this.
#
FW_IPv6=""
## Type: yesno
## Default: yes
#
# 28a.)
# Reject outgoing IPv6 Packets?
#
# Set to yes to avoid timeouts because of dropped IPv6 Packets. This Option
# does only make sense with FW_IPv6 != no
#
FW_IPv6_REJECT_OUTGOING="yes"
## Type: list(yes,no,int,ext,dmz)
## Default: no
#
# 29.)
# Trust level of IPsec packets.
#
# The value specifies how much IPsec packets are trusted. 'int', 'ext' or 'dmz'
# are the respective zones. 'yes' is the same as 'int. 'no' means that IPsec
# packets belong to the same zone as the interface they arrive on.
#
# Note: you still need to explicitely allow IPsec traffic.
# Example:
# FW_IPSEC_TRUST="int"
# FW_SERVICES_INT_IP="esp"
# FW_SERVICES_EXT_UDP="isakmp"
# FW_PROTECT_FROM_INTERNAL="no"
#
FW_IPSEC_TRUST="no"
