Public bug reported:

Binary package hint: ppp

When I log on to a certain VPN of type "Microsoft VPN (PPTP)", the
connection is always dropped after some time. It turns out that this
happens when my computer sends a GRE-encapsulated PPP packet with a
payload length of 1417. The MTU of the network interface ppp0 is 1412. I
believe the VPN gateway accepts packets with a payload length up to
1416. (How can I verify that?)

I am not sure whether pptp or pppd is the culprit here, but I suspect
pppd. This looks like an off-by-one error.

Does anyone know why this might happen? Any pointers where I might look?
Is there any information I can provide you with?

I am using Ubuntu 8.04 "hardy heron" with ppp 2.4.4rel-9ubuntu2.
