Sure.

Here is your first problem. Both eth0 and eth1 have the same IP
address AND they are on the same network. That cannot work.
If your service provider gives you 192.168.1.x network to run
PPPoE over, you should make the internal network something
different. Say, 192.168.2.x/24.

So this is your REAL external interface.

That's because Linux doesn't know which interface to use.
Re-address eth1 on the Linux machine as well as all internal
machines. Instead of using static IP addresses on the internal
network, why not try setting up DHCP? It's very easy to do and
I've documented how to do that in TrinityOS; chapter 27:
