About a week ago I posted a message about dismal perfomance on translated hosts with ipnat + natd. (20bytes/sec) This was on a 2.2-STABLE system using kernel ppp with an mtu/mru size of 296. To find the solution I tried a few things, one of them i bumped the mru/mtu up to 552. This instantly brought translated througput to 1.9-2.3k/sec which is acceptable on a 28.8 connect. I then brought down the ethernet mtu to 552, this increased the reaction time somewhat, and possibly raised througput alittle more. User ppp might also suffer from this, my personal recommendation now is to keep the mtu/mru sizes the same between the translated interfaces.
