Re: [LARTC] Firewall+NAT: only succeeds for SOME external sites??

[sebastien Robart <robart@xxxxxxx>]

i use pppoe and nat too. I have problems with 2 sites (63.238.77.237 and 
195.101.41.250) only when i change the mru option (rp-pppoe), not the 
mtu. And problem are only for box behind the gateway, directly from the 
gateway i have no problem.
seem a masq + mru bug. (don't ask me what is mru, i didn't have found 
something on it)

maybe you change mru with rp-pppoe too.
