Hello,
I am having a very frustrating issue with VIMAGE jails using VLANs on
10.1-RELEASE. I posted this earlier to the FreeBSD forum, then realized
that this is probably a better place.
Let me tell you about my issue:
If I set up my jails using a regular ethernet interface (em0), a bridge,
and epairs, everything works beautifully. All networking works as expected.
However, if I try to do the exact same thing using a VLAN interface,
everything ALMOST works, except for one thing:
I cannot communicate between the host and the jail.
I can ping in both directions, but nothing else. No TCP traffic seems to
pass. To make it weirder, the jail can communicate perfectly with other
machines on the VLAN, so the bridge itself seems to be (partially) working.
I've checked routing tables, firewalls, everything. Nothing seems to
make sense, except that something is broken either inside the bridge or
the VIMAGE code. Again, if I keep the config exactly the same, but use
em0 instead of em0.100, everything works.
Does anyone have any ideas?
Thanks in advance.
-Bill
