I understand that, and your firewall is doing what you've told it.  If a
packet comes in eth0, and leaves through eth1, then it is properly
forwarded according to the rules.

However, your rules do not specify what to do with traffic that comes in
eth1 and leaves via eth1.  So the firewall drops the packets.

The real question is, why is internal traffic seen on eth1?

Is this impossible in your setup?  I mean, due to the cabling, there is
absolutely, positively, no way for an internal host's packet to be seen
on eth1?

For instance, if you have all the computers, and the firewall, and the
external ethernet connection, all connected together to the same hub, it
might be somehow possible for one of the computers to send a packet to
the wrong interface on the firewall.  This will confuse it.

I can't think of a way that a packet from an internal network can arrive
on an external interface, unless you have some funny cabling, or
something.  It seems quite impossible.

Perhaps you could share some information about how your systems are
cabled together.
