So then I added the line
pty "/usr/sbin/pppoe -I eth0 -T 80 -m 1464"
to /etc/ppp/peers/dsl-provider, but the problem continued. After
commenting that line back out (so that no pty... -m declaration had
been made in the dsl-provider config), I was able to sucessfully
download one single e-mail from a server. There was only one e-mail
in that account and it downloaded like normal. So I sent an e-mail to
that account, being that it was on a different server from my normal
tests, but that one would not download sucessfully. So it would seem
like it had something to do with the size and speed of the one that
downloaded properly.

In short, it's still a no go and I have no clue why. The D-Link
router still works great, but pppoe from the firewall doesn't.

The d-link works... And does this also go thru the same iptables
rules as the PPPoE?

If so, then playing with iptables is only going to break something.
In any event, a run of "/etc/init.d/iptables stop" (as root of
course) will open things up and prove or disprove that theory. I
wouldn't leave it off for very long though.

If you persist in using PPPoE rather than a good router, then I
believe I'd take this problem to the Roaring Penguin folks to see if
they've a new version that fixes this, or can use you for a test bed
to see about fixing it.

No, the d-link has it's own firewall stuff. It connects directly to the
network line, in place of a modem. (Since this fiber optic service does
not have a "modem").

I tried disabling iptables on the firewall to see if I still had the
same problem, except I do not have a way of downloading e-mail on the
firewall. And since iptables was no longer doing NAT, I could not do
anything web related from my client machines. :-)

I also upgraded from a 2.4.24-2-586tsc kernel to a 2.6.8-2-386 kernel
tonight to see if it would help anything. It did not seem to have any
affect on the problem.

Thanks,
Jacob
