Shorewall users - Dec 2007 - Dual ISP

Attempting to setup a dual ISP on a gentoo box but I''m not sure how to 
configure the routing in the /etc/conf.d/net configuration file.  Does 
shorewall do all the routing or do I set just the default route to the 
PRIMARY outbound ISP?

I''d set the gateway for the primary outbound ISP, shorewall will
replace
the gateway with a multi-hop gateway anyway.

I hope that you don''t use dhcp to obtain your ip addresses from both
providers, that is problematic, the net scripts replace each others
gateways. If you use dhcp to obtain a single ip address from a provider,
then make that one the default gateway and in the providers file use
"detect" for that provider''s gateway, and just list the other
provider''s
gateway.

Both ISP''s are static, sprint and charter.  We need to get the web 
browsing off the sprint.  All i''ve done is set the charter as the 
default outbound, adjusted the providers, masq, interface, policy 
files.  Also set smtp and ssh to route OUT the sprint.

Thanks.
