Your router needs to be on BOTH networks. That is, one interface on your 162.168.0.x network and the other on your 162.168.1.x network. You need to set the netmasks to make it clear that these are separate subnets, ie. 255.255.255.0. Then the routes should be set correctly by default when you start the networking.
Turn ipchains/iptables off until you get it working and then apply them later if necessary: chkconfig ipchains off chkconfig iptables off -----Original Message----- From: rahul b jain cs student [mailto:[EMAIL PROTECTED]] Sent: 09 September 2002 14:55 To: '[EMAIL PROTECTED]' Subject: RE: How to configure a Linux machine as a Router Hi, I tried the suggested changes but it still is not able to communicate. 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.
