[LARTC] dynamic gateways

[Devin Bayer]

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.
