Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lartc@vger.kernel.org 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. seb Chris Rankin wrote: >Hi, >Yes, the problem turned out to be the MTU on the link >between the boxes.
