You're behind two firewalls...good god, preparing for nuclear war? Anyhow, most times, from what I remember, forgive me, it's been ages, but playing over a LAN requires some sort of ip program...can't remember the name of it. Something like ipconfig or that. Although I'm almost positive this clunky system has been replaced by now, so disregard if relevent.
Cool Story Bro.
Here buddie, I couldn't have you on this fourm telling people to download "Something like ipconfig or that" could I?
I don't mean to be cheeky... but here is what ipconfig actually is..
Maybe you meant a ip address related application which identified all network devices Ip's and was able to configure them so the devices that where connected to the network would not have connection/conflicting issues.
In saying this, even if such an application did exist it is still not relevant to the issue at hand, because the two users can file share.. therefore meaning the connection issue is not IP related at all. and that this issue is purely security related.
