Hi all,
I have the following problem: I have a VPN connection to an office network.
I have ICF (Internet Connection Firewall, Windows XP SP2) enabled. I have a
direct internet connection, no router or anything. The GRE packets of the
VPN connection are allowed by ICF. However, at one time or another (no
specific moment), ICF starts dropping the packets for an unknown reason (as
shown by the pfirewall.log file). This causes the VPF connection to become
unresponsive, and I have to reconnect manually to get my connection back. I
have the impression it's related to traffic, because there are days that I
can work the whole day without a problem, on other days the problems start
after several minutes.
The only workaround I have found so far is to temporarily switch off ICF.
ICF has no settings for GRE packets, only TCP and UDP. Apparently GRE
packets are filtered automatically.
Is there any way to override this behaviour, or anything else I might want
to test or change?
Thanks,
Mark Smit.
