hi, i have some questions regarding an ipsec tunnel which i want to setup between to hosts (A, B), but I want A and B to be in the same subnet. what are the possiblilities? also, i might meet the following situation: a) A 10.0.0.10 <==> ipsec_gw <==> routers <==> ipsec_gw <===> B 10.0.0.1 b) A 10.0.0.10 <==> ipsec_gw <==> Layer-2(switches) <==> ipsec_gw <===> B 10.0.0.1 can anyone give me a clue on the 2 stiuations? in (a), i just want an ip sec tunnel, but the endpoint hosts being in the same subnet. in (b), same situation but i don't have routing between the ipsec boxes, only switching. can i tweak some bridging and netgraph setup for that? thank you very much. -- Key fingerprint = C549 46E1 1B75 116E 3321 BC0A E502 9457 319E B340
