pls instal ICQ or xfire:) than we can talk outside from Forum:)

sry i'm not playing necrovision on my pc, so i wont install anything.
But when i ll have a pc mine (with starcraft2 and diablo3 of course) :-P i will surely reinstall xfire ;)

We tested both versions, and they are fully compatibile. So the problem seems to be in your internet connection or some firewall issues of smth else.

when poisonivy tried to join me, game said "error nat negociation" and said poisonivy was "v1.0nv2"
that's strange

before i've seen that when we writhe cdkey in minuscule, it doesnt works
but when we writhe it in majuscule, online works... strange ? or i'm wrong ?

Really have no idea of the problem, sorry

I've never player nvn online, but just in case, NAT=Network Address Translation, in most cases thoses are firewall issues.

Besides I'm very surprised to see this "v1.0nv2" as [badmounthing farm51]. Poisonivy, what do you have after "Cfg.Version =" in config.ini?

Cfg.Version = 0.01 <----------- ????
My FW is shutdown
i have look and the router is no problem...
when i host a game, and other will join, is see Ping time out or he has other version ???!!!???
i will make a screenshoot from msg (console)

That is normal, I have the same value.
Does that mean that you correctly configured port forwarding? According to config.ini necrovision uses port 3455 (TCP? UDP? both?).
Googling for "3455 port" reports that port 3455 is also useg byt the rsvp service, which is a "signaling protocol that allows the sender and receiver in a communication to set up a reserved highway for data transmission with a specified quality of service." Maybe we should consider using another port?

hm, i have read the port 3455 by google, t connects via port 3455-3456 and then stops and times out.

ok, but other port? wich?
in other online Games i can join and host a server....hmpf

You can host a pk game without trouble? W've got a problem there, sounds like my theory was wrong after all...
Just in case, did you somehow associate pk and port 3455 somewhere? (like blocking all traffic on port 3455 that isn't going to painkiller.exe...weird as firewall is off)

I'm out of idead for now, maybe you can try messing with:
Cfg.ConnectionSpeed = 4
Cfg.LimitServerFPS = false
Cfg.NetcodeClientMaxBytesPerSecond = -1 (-1 can mean no limit or be a mistake try putting an huge number 1000000)
Cfg.NetcodeLocalPlayerSynchroEveryNFrames = 1 (maybe 1 is a bit small->10)
Cfg.NetcodeStatsUpdateDelay = 1000 (if ping is in the stats...)
Cfg.ServerPort = 3455 (that won't hurt)

As you have PK, you could compare their config.ini. And if you don't find anything revelant, PM me pk config.ini, I'm kinda curious to see it anyway (you may wish to clear profile&player name, server password, etc).
