Hello, Chadha: You do not show how you attempt the 'ping', nor the error message.
Please show exact ping command attempt. Please show output of 'netstat -r -n'. Both cards (should not, cannot) be on the same subnet for the 'firewall/router' to function. The 'firewall/router' should show a route to the local LAN (eth1) for all addresses as 192.168.x.y and a default route (0.0.0.0) to eth0. An old 'netstat -n -r' of mine looked like: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 67.39.15.254 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 67.39.15.254 0.0.0.0 UG 0 0 0 ppp0 In the above case, ppp0 was a ppp-over-ethernet association with eth1. You should mask out your real IP address for security (if static). HTH, Chuck p.s. I have never understood the signature threat! ? ! ? Perhaps a separate email identity for public messages?
