Maybe.  Multi-wan definitely works, I fixed it up within an hour or
two of getting my second WAN connection at home. Create rules and
choose the gateway to send the traffic in question.  VPNs are a
different story and something I hope to find time to work on during
our hackathon.  We may or may not do what you want, I'd need a little
more info on the exact setup you envision.

Maybe...it's been in tree for a long time, but I know of no-one using
it.  It'll likely get a workout at the hackathon to ensure that it
really is working.

I don't really know anything about m0n0 or FreeBSD 4.11...what were
the issues?  I do wish that FreeBSD tied IPSec tunnels to a logical
interface like OpenBSD does, but I hear we can do "stuff" with gif
interfaces.  I plan on looking into that soon as filtering over VPN
today kinda sucks w/out an interface to apply a rule to.

We've got an snmp daemon.  Dunno if anyone is running it over IPSec
but I don't see why it shouldn't work assuming your tunnels are setup
correctly.

Similar issue.  Traffic shaping (queuing) can only happen outbound on
an interface (you can only queue what you know about :)), since IPSec
doesn't have a logical interface, we can only shape the ESP/AH
traffic.  This may or may not work in the future.

:)  CARP rox :)
