Do a 'ipchains -l or -L' can remember which. This will tell you what rules are currently running. Look at the Ipchains man page that should tell you how to remove all the rules so that you can continue testing. I think it's 'ipchains -F'. Sorry I don't have a concrete answer for you but it's been a while since I have used ipchains....

How do I check whether packets are not being blocked by ipchains/iptables ? I had one more question. To eth2 I have given the addr. 192.168.0.13 and to eth3, 192.168.0.14. Since eth3 is also given a 192.168.0 network addr., during startup the routing table has the following entry for eth3 Destination Gateway Genmask ------ iface 192.168.0.0 0.0.0.0 255.255.255.0 eth3 I have to manually delete this entry and make the destination 192.168.1.0. Cant I do this permanently ? Many thanks, rahul.
