rp-pppoe 3.5 & poor performance

Hi,

I have set up a Linux system as a firewall.

I have been trying to figure out why I have slow response from web sites to my Linux systems behind the firewall. Often a page will never completely load. e-mail and newsgroups seem to work ok.

I am using Roaoring Penguin pppoe v 3.5 under Slackware 9.0 on the firewall. I have followed all of the suggestions in the documentation without any success.

Is anyone aware of any gotcha's of which I should be aware?

Is there an alternative to rp-pppoe with which someone has had success?

Thanks,
Randy

Make sure you are not using rp-pppoe synchronous option (maybe that is for
sdsl). Using that option for adsl caused errors in ifconfig (but no
noticeable slow down). If you use a graphical interface like tk-pppoe,
that can eat cpu time (I think 20-30% on K6-2/400).

Kernel pppoe uses less resources (no noticeable cpu time), but I am not
sure how to configure it, because SuSE makes it all too easy.

Are any internet file sharing programs running on your LAN? If your
upload becomes saturated, that can choke your download (acknowledgements
for received packets have to wait in line in upload queue).

Thanks, but I am not using the rp-pppoe synchronous option. There is no other traffic on the LAN. I am testing using only two computers. One is the firewall and the other is the system I'm experiencing the problems on. No othere services are running.

I'm wondering if the problem could be the NetGear FA-311 NIC I am using to connect to my ADSL modem. mii-tool should the connection as 10BaseT-HD, which I believe is correct.
