It does not work without, at the router end.

Exactly. But I connect to a switch and hence expect the behaviour detailed above. Now, it is my suspicion that the apparent need for promisc at the router end indeed is an apperent one and not really the router's fault but rather the other end's. The other end, in this case, is the server below. If the server, with its single MIB, default-routes its packets through one specific of its vlans which may not be the one, at the router's end, with the corresponding IP network the traffic entered into the net, would it be possible that there's something preventing them be received? Unless there's promisc on, of course... I'll grab the laptop next time I think of it and have the switch monitor traffic to it to see what really is on the wire, maybe that helps and gives me a clue.

Which effectively means that I do need FIBs. I agree that this behaviour might make some sense :) > Something like, "setfib 10 jail $JAILOPTSANDARGS", > in the jail case.

Read the message for > revision 1.1485 from here: > http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/conf/NOTES I have seen that section as a separate posting [1] which is why I suspected to possibly be able to resolve my issues above with it. It is my intention to insert 4 to 8 FIBs asap but I currently don't know when I take my time doing so. Generally speaking, or rather, inquiring, has anyone ever done FIBs with ezjail? It probably is very easy, and I consider(ed) looking into it myself but I currently spend about max. an hour every 2-3 days on FreeBSE so I don't really progress. Well, might eventually, but that'll be dunno when. But well, such is life, and this is pleasure not work :) and I hope to learn something useful on the way. Thanks a lot, and All the best, Peter.
