Sorry, I don' t understand what you mean by "reallow all connections". After -F, the tables are flushed, what means that you have no rules in your firewall. So, everything depends on the chains' policies of the "filter" table.
In principle, the starting policy is ACCEPT, but -F does not change a table policy.
I know that Fedora Core X comes with a pre-set of rules in the firewall, and the policy is explicitly set to ACCEPT in the chains of the "filter" and "nat" tables. I don't know about other distros.
So, in FCx, iptables -F should allow all connections.
