gateway.foo.com and ppp.foo.com seem to be routing without a problem.
I make this assuption as I have accomplished various tasks on
dialin.foo.com - ie:
mail traffic is flowing both ways
I installed squid and used it as a proxy from gateway.foo.com
I have installed apache and used it as a www server from
gateway.foo.com
the only communication problem I have is between dialin.foo.com and
gateway.foo.com - I cannot ping one from the other.
To try things out I setup temp.foo.com directly to gateway.foo.com.
Again, I was not able to ping temp.foo.com from ppp.foo.com.
Cheers,
Alek.
