Howdy list,
Thanks to mulix, my Linux ADSL connection is up and running. Next, I set
up IP masquerading, and encountered the following odd problem.
When conneting from some host on the LAN, every time the remote host
tries to send "a lot of data at once" (a large TCP packet, perhaps?),
the masqu
reduce the maxmtu of the win boxes to 1452 and they will work fine.

Hello,
I tried reducing the MTU on the client box, and it doesn't help. I can't
see why it should -- the problem occurs when the *remote* host is
sending a large packet *into* the LAN.
Looking at captured network traffic both between the masquerading box
and the ADL modem and between the masquer

Eran,
use mru 1542 and mtu 1542 in your pptp command to reduce the packet size
received from the peer.
This is updated in the new HOWTO

Thanks! Works fine for me, once I convinced those Windows boxes to pay
attention to their MTU settings (hint -- if you create the W2K registry
entry as String instead of DWORD then W2K will silently ignore you, and
I know no easy way to get the currently used settings...).
Sheesh. Automatic MTU
