So, what is your underlying network > structure, do you have multiple interfaces or routes that change etc ? It's a one NIC machine, only having a route for it's own subnet, and a default route to a gateway there. Plus for loopback. In the kernel I have the following network options in addition to GENERIC: options IPFIREWALL options DUMMYNET options BRIDGE options "ICMP_BANDLIM" options IPDIVERT options IPFIREWALL_FORWARD (I don't need BRIDGE and IPDIVERT though.) -- Anders.
