I have the same problem, mss clamp isnt working.
I dont know which i have kernal or user, i just did
aptitude install pppoe pppoeconf
on a up to date etch box.
then at the mss clamp pppoeconf dialog i said yes, clamp to 1452. However the dsl-provider file did not uncommment any of the pppoe lines as it says it should in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=425448
8<--------------------------------
#pty "pppoe -I eth0 -T 80"
pty "pppoe -I eth0 -T 80 -m 1452"
#pty "pppoe -I eth0 -T 80 -m 1412"
8<--------------------------------
Nor does it add any pppoeconf adjust '-m MSS' to provider file.
" When you use pppoe support in the kernel
(like you), pppoeconf add an iptables rule in your
/etc/ppp/ip-up.d/0clampmss file. "
This file exists but does not appear to be invoked anywhere.
find /etc -name '*clamp*'
/etc/ppp/ip-down.d/0clampmss
/etc/ppp/ip-up.d/0clampmss
grep '0clampmss' /etc -r
nada
grep '1452' /etc -r
/etc/ppp/peers/dsl-provider:#pty "/usr/sbin/pppoe -I eth0 -T 80 -m 1452"
/etc/ppp/peers/dsl-provider:# don't work using -m 1452...
more nada
iptables -L FORWARD -vn

How do i tell which mode im using?
Is the package broken or did i use it wrong?
And could the man page be clearer about mss, the two references seem to
conflict, one says (vaguely) about using mss and further down the other says
you should change your lan clients aswell. mss is a hack but seems to be a
necessary evil with pppoe.
Lastly is there a definitive pppoe on debian howto any place?
Thanks
Peter
