IP forwarding problem - BulleT - 03-23-2010 06:26 AM
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?

net.ipv4.ip_forward=1
net.ipv6.conf.all.forwarding=1

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
