A "senior" tech-support person once told me that i should add the 'adjust-mss 1452' command on a cisco 827 PPPoA, for a smooth connection with the network, and that it because of the NAT. he didn't say why exactly..
As far as i know, incoming NAT doesn't limit the packet size (correct me if wrong) and therefore i shoudn't put this command.
Any ideas ? experience ? anything?
