[FW1] PPTP session trough FW-1 hangs-up after 10 minutes

["Robert Rinnberger" <Robert.Rinnberger@FW1-NOSPAMmch.sni.de>]

Hi,

I've problems with a PPTP-connection from a MS client in the internal
network and a PPTP server outside.
I use static NAT for the client and allowd IP 47 and TCP 1723.

This connections worked propperly, but since one or two weeks the client
session hangs-up after exact
10 minutes and the client has to redial. After 3 or 4 times redialing, the
client must be rebootet. So, I've
nothing changed at the firewall policy and the customer told me, that no
changes were made to
the PPTP-client and the PPTP-server.

I'm not sure, if this is a timing problem of  the firewall or the PPTP
connection. Any ideas?

Thanks,
Robert
