No. Well, sort of.
I considered writing an over-ride to the automagic IP grep'ing from
ifconfig, allowing you to enter it by hand.
I think that this would be the most obvious solution, as somebody that
plan's to run internet service's from behind an IP-MASQ'd firewall will
probably be quite capable of telling 'setup' their network topology - I'll
write it in & update the tarball...
Thanks very much for the suggestion, I'll write in a couple of IP-MASQ hints
into the file... :-)

Sorry about lateness of reply, had a great weekend digging up a friends lawn
