(ASCEND) P50 routing on LAN side
I've had my P50 up and running for what seems like years now (and may very
well be so). The connection has always been from a LAN numbered within
our provider's supplied Class C through a Centrex connection.
All was well.
I then installed a firewall and for that purpose moved the P50 to a direct
connection with the firewall's external interface via a crossover cable.
Again, all was well.
Now, however, I'm trying to configure some external plugs through the
firewall to an SMTP host on the internal side. The firewall is all set to
go, but the routes don't seem to quite be there on the P50.
A ping attempt to all IPs in our class C fails, except that of the
firewall. Normally desired behavior, except for the case of the SMTP
server.
What's happening is that I can see the ARP request make it all the way
through from a shell account on a different provider to the P50 and then
on through to the firewall. What the firewall manufacturer tells me is
that I need to have the P50 configured with a static route pointing to the
external interface of my firewall as a router for the class C. But the
P50 already establishes a /24 route to the ie0 interface:

255.255.255.255/32 - ie0 CP 0 0 0 643
So something like "iproute add 207.176.66.0/24 207.176.66.40 1" won't
work--the existing route will always take precedence.
Any suggestions here or insight as to what I am missing? Thanks In
Advance.
