Here is the situation Private ----------- Debian --------- ISP LAN eth1 eth0
Simple and clear. I used ipmasq package to do the job. And it worked perfectly with 192.168.0.0/24 network for private lan. Then i switched private network to 10.0.0.0/24 and suddenly it stopped working. Not whole network, but masquerading only. I still can ping from debian in both ways. I can even ping external interface from my internal network. But i cant reach anything further. Packets aren't denied and logged. They are simply gone. I set up simple masquerading with no firewall rules at all with default ACCEPT on all interfaces and again it works for 192... and does not for 10... Even simple forwarding fails for 10... I tried it on potato box (i386) and woody box (celeron) effects are the same. Does anyone know what is the problem? Thanks JA
