Hello there,
I’m using a home server to test my maps and sometimes invite someone to my server. My server isn’t shown in any browser I know of (ET, ASE and splatterladder.com) and when you add this to your favorites it always appears to be offline. Some people can’t even join my server for some reason and all they can see is Awaiting Connection…
This isn’t my biggest problem. Yesterday some guy from my provider came over, installed a new modem (Cable) and resetted our router. 
Now I have a new IP and I changed some stuff to get my server working again. However, when people join my server with via my WAN IP, their ET starts to lag over 999 ping when I see the WeaponStats command in my console. All they can do is /reconnect and their ping is normal again. When I use my internal IP (192.168.2.103:27963) I have no problem at all.
I can remember that I had such a problem in the past, but for some unknown reason that problem got solved.
I’m using the latest patch and the latest ETpro for my server. I don’t use any other mod and my sv_pure is set to 1. I’m using a server.cfg file and a .config file.
The problem occurs frequently, so it’s a real pain in the ass for the clients.
Here’s some piece of my logfile:
23:53.19 ClientBegin: 0
23:53.19 WeaponStats: 1 0 0 0 0 0 0 0 0
23:53.19 ClientDisconnect: 1
23:53.19 ClientConnect: 1
......
23:54.38 WeaponStats: 2 0 0 0 0 0 0 0 0
23:54.38 ClientDisconnect: 2
23:54.38 ClientConnect: 2
If you guys need more information to be able to help me, please tell me.
Thanks for the help in advance.
