[SLL] Bridging two networks

[Ralph Sims]

I'd be happy to use whatever works at this point.  

I'm using a dynamic dns service to keep the DSL IP mapped to a hostname, so
that end is taken care of.  The computer is 10.0.0.2 and the "other" network
is (example) 1.2.3.4/26 with a gateway of 1.2.3.254.  IP forwarding is on
(and again, no filters).   I "own" the 1.2.3.0/20 network so I can do just
about anything I want from that end.  So, with ip forwarding and routing,
logging in to the linux box on the DSL line should give me access to the
1.2.3.* devices.  How can I route between the two?   At this point nothing
goes in or out of eth1.
