Networking woes, I cannot understand

from Sins Forums
Alright, so my friend bought this game a while back, and suggested I do the same so that we can play.  We do not live in the same place, nor do we use the same internet connection.  Everything was going fine, however an anomoly occurs we cannot figure out.  We cannot ever be in the same game at the same time.  Both of us own our own copy of the game, nothing we have should be conflicting.  We can both join other peoples games, but only if the other isn't in it.  The moment one leaves, the other can join withing getting the "disconnected from server" error.  This has happened in Universe at War as well, but other than these two games, never before.

We've been gaming for 8+ years now without this happening.  We've been gaming with this exact setup for about a year, and now all of the sudden this happens.  We are still able to play Born of Blood, Warcraft Three, Supreme Commander, and Civ4 without problems.  Does ANYONE have any ideas?

Monk may have a better idea but both or one of you dont use a nat router by any chance? Its just Ive heard of certain nat routers not being able to negotiate connections with other nat routers. Once again maybe Im way of but that would be one of probably many reasons to why you and your friend can join independant games but not together.

sorry about dp, edit button again but I can see you are saying you can get in many games, something to do with the netcode + the router. Not sure though tbh

redwing may be right. I would try just one game where both of your PCs are connected directly to the modems.

I have an odd issue on BNet where if my brother or myself host a game we can't join UNLESS we join someone else's first, very strange.

I think I have had that issue with C&C generals on an older router waay back, Im sure c&c generals uses P2P as well, also another option but I would try the modem first is to go into something like virtual server settings on both your routers and both go into command prompt on your seperate machines, do ipconfig /all

go into your router admin web interface, into virtual server settings or the alike and look for an option DMZ and put the ip address in e.g 192.168.1.253

Your friend should also do the same on his router for example say his ip was 192.168.1.252
he goes to the page with the dmz option, selects it and puts his IP in as well , that way both of you have all your ports open

Sure someone will say thats badly insecure but to me its a great way to initially test that it is possible for your routers to work. Try modems first without routers,next try both on dmz then if that works try port forwarding . The thing is some nat routers the more recently bought ones have an ip stealth type option so you may need to turn that off.

Good luck with it, I remember when I got my first router it was a pain in the butt lol

Keep at it just test one little thing then refine , its a pain I know :)

As a last resort but you really really really need to know your exact router model and equally so your router version is look for updated firmware. Definatly dont jump into that though, while I have never had any botched firmware I told my friend which one to get one time and I dont know if he got the exact one but he fried his router.

Good call about the modem evil that is one sure way to check if its the routers.
