Connecting to an internet game from NATed LAN/same external IP address

[Spikeone]

When I connect to a game hosted by a player in the same LAN as I am it is not possible to connect. Therefore the external IP addresses need to be compared and if they are the same the local IP has to be used

This behaviour is known,

the problem here is the buggy nat-forwarding (with my router i.e it does work)

but i'll try to find a way to avoid that.

another possibility would be playing over ipv6 (for example activation teredo 6to4)

Yeah, but relying on a router with non-buggy NAT sadly isn't a good way. I even thought it is a good one. Let's hope IPv6 will be the default soon an we get rid of NAT.

the problem is: the lobby does not know the internal ip - we could perhaps only "allow" to change the ip if the host's "on" the same external ip

What is the external ip address actually used for? Just for identification?
(I'm just asking because I might try to solve this one.)
