Frequent disconnection of adsl on fedora...

Hey everyone.
I've recently changed to a Linux box for my gateway (Fedora core4 test2) and I seem to be getting disconnected far too often (sometimes after only 20 or 30 minutes!).
I know my ISP isn't the problem because I've been connected on a different machine for a few weeks without a dropout.

Any ideas based on my ifcfg-ppp0 file?
I've put some ppp.log info at the bottom of the post too.
Thanks for any help!

Hello,

I had to look for this myself, it could be this one:

PPPOE_TIMEOUT: If this many seconds elapse without any activity seen by pppoe, then pppoe exits.

The meaning of the rest of the commands you can fine on http://linux.about.com/od/commands/l...l5_pppoeco.htm

The pppoe_timout variable is not in my ipcfg-ppp0, so I suppose you can delete ir.

Bye

thanks, ill try that out :)

I fixed the probelm.

My IPtables were a bit too strict.
I think PPPoE wanted to ping my ISP every so often and I had blocked some ICMP messages in certain directions.

This caused PPPoE to assume my connection was inactive and so disconnected it!

so to anyone reading this thread, check you iptables :)
