Your routing table looks strange. You have two entries for the 192.168.1.0 network -- one without a gateway and one with a gateway of 192.168.1.3. Try removing this gateway on the internal network to make your routing table look like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 146.115.74.0 0.0.0.0 255.255.254.0 U 0 0 0 eth0 0.0.0.0 146.115.74.1 0.0.0.0 UG 0 0 0 eth0 -- Lee Bradshaw [EMAIL PROTECTED] Texas Instruments [EMAIL PROTECTED]
