Wellif you're doing bridging on the Linux setup you're trying to replace, but don't realize it, forget to mention that the Cisco actually *does* have an address in the /29 the Free/OpenBSD box lives on twice, and then have a conceptual breakdown between layer 2 and layer 3, you might end up where the OP is. At least that's the conclusion I've tentatively come to given the parallel conversation on freebsd-questions. :-) I think he's trying to do a bump-on-the-wire firewall. Here's OP's network diagram from freebsd-questions, with one correction based on a later clarification: +---+ | Cisco | +-+-+ |if: 189.92.72.9/29 | |em0: 189.92.72.10/255.255.255.248 +-+---+ | FreeBSD | +-+---+ |em1: 189.92.72.11/255.255.255.248 | | +-+--+ | Switch |+-+ ++| MAIL | |---+-+ bnx0: 189.72.92.12/255.255.255.248 Looks like a stereotypical bump-on-the-wire bridging firewall to me. Dante: see http://www.openbsd.org/faq/faq6.html#Bridge And in OpenBSD I'd address only one of the interfaces (or none of them if you wish to increase security by forcing all management to be done from the console). And it's not routing. So don't try to use routes. --Jon Radel j...@radel.com [demime 1.01d removed an attachment of type application/pkcs7-signature which had a name of smime.p7s]
Re: Static routing question
Hi This is a part of the output containing the static routes related to *bnx0* , *bnx1 *, i was trying to make a static route for the 189.92.72.11 pointing to *bnx1* but without success, is it possible ? below the routes is the output of ifconfig these interfaces, i'm gonna try a bridge also.

Re: Static routing question
That is not supported. You MUST NOT have IPs in the same range on different interfaces. You can assign some /32s (or /128 if you are using IPv6) to a lo1 on the system, but that may not be what you want. On 2014 Nov 06 (Thu) at 19:12:20 -0200 (-0200), Dante F. B.

It is absolutely correct that 4.9 is long unsupported, but running 5.6 or -current is going to make no difference to the problem that Dante described. phessler has it right; I have one thing to add though, this might be a situation where a bridge(4) can help.

When someone submits a bug report regarding an old release, we can go around and around in circles finding out if it is still valid. Or we can shotcut the problem, since there aren't enough people to verify things. Since I value my sanity, I saw that report, and I ignored it.
