Nope, all IP interfaces on one machine must be in different IP networks. (The only exception: for p2p interfaces (SLIP, PPP), the IP address of the remote end counts, while the local one can be duplicated.) For me, it would seem to be best to use a 192.168.something net between router0 and the FreeBSD packet filter, but of course, this requires some minor reconfiguration on router0 (which turns into a major reconfiguration since router0 happens to be an Ascend P50, which has a rather confusing terminology and setup screens when it comes to something like this -- been there last week, done that). Note that the WAN-side IP address of router0 would remain unaffected by this, so there's not much visible about this reconfiguration from your ISP's point of view, except traceroute will trace one additional gateway with some 192.168 address. Failing this, maybe you could do some cute and clever tricks with divert sockets, natd, and explicit host routing out an Ethernet interface, but all this looks rather hacky compared to the above `transit network' solution. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
