[isalist] Re: Adding another internet connection

http://www.ISAserver.org
-------------------------------------------------------
  
Just to be pedantic here-- While only one connection can have a default
gateway, and only one instance of the "External" network concept can exist,
you can certainly have multiple connections to the internet with ISA if you
are willing to manage the routing for what would be the "special"
connection. ISA would only see one as "the Internet" but routing is routing.

The OP's layout is actually conducive to this type of configuration, as he
wanted general Internet for one connection, and specific publishing (Like
SMTP) for the other.  That is do-able - kind of like Moffat's "dedicated
DSL" solution.

But yes, two "general connections to the Internet" won't happen.
