Everything works well except I can't use tcpdump(8) on the gif(4). IIRC it's a well-known problem - I already saw this topic here but can't find these posts again - but I cannot understand why it doesn't work since if_gif.c in RELENG_4 has bpfattach(), bpf_mtap2(), ... Is it supposed to work or not ? If not, does it work on RELENG_5 ? My very -CURRENT laptop succeeds in opening bpf(4) on a gif(4) interface. Regards, -- Jeremie Le Hen jeremie@le-hen.org
