below are the (mildly edited) routing tables. my local home machines
have 192.168.0/24 addresses and are accessed via en1. my work machines
have 10.10/16 addresses and are accessed via ppp0.

Internet:
Destination        Gateway            Flags    Refs      Use  Netif Expire

this is correct.

i have DNS setup to resolve work addresses via placing an entry in
/etc/resolver. i can ping work hostnames and have them resolve to the
proper work addresses. to dig work hostnames, i have to explicitly
tell dig which nameserver to use (it doesn't seem to respect the
entries in /etc/resolver).

yes. the wireless is first in the list. note that if i move VPN to be
first in the list, the VPN proxy settings are used, but then *all*
traffic goes through the vpn interface (which i don't want).

i'll reiterate that i'm not having a problem routing traffic to the
VPN interface. rather, i'm having trouble getting proxy aware
applications (like safari) to use the proxy settings for the VPN
network port when accessing addreses serviced by that port (e.g. my
10.10/16 work addresses).

Thanks,
nall.
