I did this also at one point, but switched to looking at nos-tun now in
3.0 and 4.0.  It has the advantage of not being home-rolled; I never
implemented some of MTU handling code described in the relevant RFCs.
Although, to be honest, I haven't checked if nos-tun does either :-).

May need a little more information.  What kind of errors are you seeing
from Coda (take a look at /usr/coda/etc/console, as well as venus.log in
the cache directory).  Coda does not like multiple interfaces very much
for a variety of reasons; if it's a machine using tunneling, that might be
related.  What version of FreeBSD are you running, et al?

You may want to send questions to codadiscuss@coda.cs.cmu.edu as that is
usually more carefully followed by the coda folk,.
