Connection reject Games / Download Program etc.

Hey guys! since 2 days i've got a new modem. Now i can't use Paintball 2 or other games for playing on public server. I don't know what's the problem. Someone had the same problem before? The provider send me this router cause we got a too old router. It's the same Connection (only new modem)

Routerdata: ZyXEL P-660HNU-T1

Hmm.... interesting. Maybe it has a routerside firewall. Try to access the router's admin panel (usually 10.0.0.1 or 10.1.1.1 or 192.168.0.1 or 192.168.1.1) and disable that firewall.

Propably the router limits traffic to HTTP only.

What can i do about it?

I've just had a Teamviewer session with him, the router blocks all outgoing UDP traffic regardless what filter / firewall settings are set (or at least all outgoing UDP traffic ist blocked, I don't really know if it is the routers fault). He is going to contact the support, hopy they can sort that out.

I would run tracert 8.8.8.8 and check where it gets stuck. (open cmd then type "tracert 8.8.8.8"

He contacted the support, they had to set up his firewall remotely. Seems like the settings you can do locally in the router configuration don't have any effect. It works now.

Windows tracert uses ICMP packets according to Wikipedia, so that wouldnt really help. We could receive answers to pings to paintball servers, so ICMP traffic was not blocked.

Really? Doesn't it use UDP? When UDP was blocked in my school Wi-Fi, i wasn't able to ping anything.

Traceroute, by default, sends a sequence of User Datagram Protocol (UDP) packets addressed to a destination host

/EDIT: ok you're right, the Windows tracert uses ICMP, linux uses UDP.
