So, before I get the canned response... PortForward instructions are completely unhelpful for the Actiontec modem, as it is assumed I'm using Windows (which I'm not). I am using the Actiontec 1520 as an Ethernet DSL modem with "Non-Windows setup" in RFC1483 Bridged mode (not Routed). DHCP/NAT is used on the LAN side to run multiple LAN devices, if you believe the Actiontec setup menu.
I get the typical message about Low ID, behind a firewall (which I'm not), etc.
I've tried to use Advanced setup (from PortForward instructions) within the modem for port forwarding, but this is repeatedly unsuccessful. IP and DNS are set to Static. Each time when choosing the ports, I cannot enter the correct static IP. The modem simply refuses, giving the message "IP should be in the same subnet!" Directions from here are unclear. Actually, they're non-existent.
At any rate, since I've no software Firewall on, how do I negotiate the correct NAT to get aMule to work with a High ID, and all its attendant creamy goodness?
Could I get some help that's actually germane? I mean, if it's not too big a deal...
