Re: firewall blocks ppp0?

[Ray Olszewski]

OK. Just as a reminder ... I don't run Red Hat here, and I don't currently run PPPoE on my Debian-based router. So I can't help with specifics at the level of what config file the RH-8.0 version or RP-PPPoE uses.

Having said that, I think you yourself have spotted the problem. A severely edited version of your report, below, focuses on it.

The problem you have here is with the -T setting. It tells pppoe to exit if there is no link-layer (ppp) traffic for 20 seconds. As you go on to comment ...

I don't understand why a successful connection results in a
hangup. The -T timeout option of 20 seconds seems about the time it takes for
my connection to die. I gather that timeout can cause trouble if
there's no traffic. The solution is to use lcp-echo-internal option
for pppd. The pppoe timeout should be about four times the LCP echo
interval. Any idea where one implements the LCP echo option?

This is a pppd option ("lcp-echo-interval", not "lcp-echo-internal", BTW). Put it wherever the RH-8.0 implementation of pppd stores its settings (on my Debian system, this would be in /etc/ppp/options, but YMMV ... check *your* version of the pppd man page for this info).
