IP forwarding problem

[BulleT]

Behind one of my ip addresses, I have routed a subnet. Something is wrong with iptables because it wont let me make any trafic at all trough that subnet.

What's pulling me back?

have you enable ip forwading in your sysctl.conf?


net.ipv4.ip_forward=1

net.ipv6.conf.all.forwarding=1

As i last checked ispcp did use iptables only for traffic accounting...

I checked that, it's fine configured.

Still...

I think you have a routing issue here (not even remotely related to ispcp, btw). Expired TTLs make me suspect that the packets enter a loop where they are being forwarded back and forth until the expiration. Check your routing setup...

It wasn't my box's fault. It was the ISP's .

Thanks
