Re: [TCLUG:8342] Multiple Ethernet

["Brian J. Ackermann" <brianj@subrad.com>]

Well, let me see...in the netconfig(redhat 6.0) panel, ip forwarding is checked.

As for everything else, this machine is (going to be) the gateway machine,
unless I'm really confused on things, which is likely the case.  Right now
all I have is an ISDN router (Ascend Pipeline 75, I believe) that does our
gatewaying...

My plan was to plug a hub to the router (so that a few boxes could be outside the firewall,
should I want that later.) and off that hub, have this firewall box be a bridge between the office
and the router.  I assumed that would mean that I would make the firewall box also become
a gateway.

Am I wrong?

Looks like I've got lots of work to go....

Yep.  You probably don't have IP Forwarding enabled.  You might alwo
want to check and see whether you've enabled firewalling on your
gateway machine.  In all actuallity, you've only given physical info
on your network.  We really don't know what you've done on the
gateway.

Later!
