Hi, I'm trying to troubleshoot NAT on a VLAN interface (parent interface is xl0 - a 3com 905). With OpenBSD 3.4 I got a 'initialized with non-standard mtu 1496' message with the same interface card, but with 4.1 this disappeared.
Does this mean "everything is fine, this card supports VLAN trunks", or should I be dubious and use something else (which one)? I am not able to provide debug output at this minute, but essentially I can't seem to do NAT when vlan0 is set as the external interface ($ext_if; the suggested nat line in pf.conf(5) is used, with ext_if="vlan0"). I can get a DHCP address on the interface, and I appear to be able to connect to anywhere _from_ the host, but not through it. A 'pfctl -s all' only shows me the static mappings (rdr's). Is my question too broad? I'm running 4.1 GENERIC, and the inside interface is a dc; Linksys I think. I can provide debug/configuration output once I am in a position to do so later if this helps. Thanks, Tor
