I agree that thats ummm unusual ...
My ISP has just done bridge to pppoe saying telstra mandated the change by
changing layers so maybe a bridge connection is unwise (short lived option)
if you do
ADSL-Router.............Server (- - - other network - - -)
.............PCs
.............Hub..........OtherMachines
.............
You achieve everything. Unless you WANT the server to access another network
and WANT to do firewalling, don't bother.
Your router may be configured to VirtualHost Ports onto the local network or
even allow a DMZ machine [ie all ports go to that machine] but except for
that the router forwards NOTHING so a firewall is not required as the router
is a total firewall (except what you specifically allow)
ADSL traffic is a fart-in-a-fan-factory so if you need LAN bandwidth do
whatever to address the need.
Hey, you're having fun, do whatever, but this is ummm confusing
