Hi,
I have a problem with my pppoe dsl connection on my linux firewall.

There are many sites that i can't access (https://forums.gentoo.org for exemple). I thin that it is a problem with the MTU values on my interfaces.
I have set the ppp mtu to 1412, 1492 and 1500 and many others but the problem still exist.

thanx for helping me.

make sure that your TCP_ECN is off in your /etc/sysctl.conf
