Thanks for the reply Jack. This many work. The LRP does not need to NAT or
be a firewall, its only use will be to join DSL and Cable. Like so.
-> DSL
LAN <-> Router/NAT/FIREWALL <-> LRP <
-> Cable
I will check out Equal-Cost multipath routeing on linuxdocs. I have
encountered another problem, that I have sent to the list already, getting
two external interfaces to use DHCP. I will probably need some help or
directions to docs for turning off all firewall stuff.
Thanks again,
David

Subject: RE: [Leaf-user] DSL and Cable combination question
Well, maybe listen-only BGP would help (see zebra.lrp), but probably
not since you're still doing NAT and it will hose TCP communications if
half the packets are masq'ed with one IP and the other half are masq'ed
with the other IP. Not to mention that I still haven't been able to
get any Linux box to masq on two different external interfaces --
masq'ing N internal interfaces behind a single external works, but
multiple externals doesn't for me.
The problem is that when you have two circuits to two totally different
networks, the router has to send the traffic belonging to a given
session on one or the other pipe in order to avoid breaking a lot of
assumptions -- unless you're doing NAT before it even gets to your
LRP... hmm, just thought of that...
-> Cable
LAN <-> NAT <-> LRP <
-> DSL
Now the LRP can safely round-robin its two external circuits without
breaking anything. All you need to make that happen is equal-cost
multipath routing, which is explained nicely in the Advanced Networking
HOWTO on www.linuxdocs.org.
Man, I'll have to try this myself after the kids go to bed :-)
