Hello.  I''m glad this list is finally back up.  Good job whoever is
is responsible.  I wanted to ask this question months ago because it
would save a fair amount of work.  But I''m still curious about
implementing this idea:

All replies will be routed back through the same host they entered
from, instead of the default gateway.  This is the similar to the
idea described in the LARTC HOWTO section 4.2.1: Split access.  The
HOWTO describes automatically associating the source address of
incoming packets with the gateway they entered in and using those
associations for replies.  The difference is that instead of the
gateways being statically defined, whenever a packet is received the
previous hop is added as a gateway.  It would also have to be
connection-oriented, not address-oriented.

So what are people''s ideas on this?  I couldn''t find it being
done
before, but it seems to only make sense.  It''s just something I was
thinking over to help ease the administration of the situation with
multiple gateways.  It would become basically config-less if this was
all dynamic.
