XP SP2 Firewall Blocks VPN

[Steve Mulhall]

Hi all,

New to all this and only a little technical, so go easy.

Just installed XP SP2 on my laptop and it appears that
the new firewall blocks my VPN connection into my office
network. There is no message to say it is being blocked,
but I simply cannot connect to the network until the
firewall is turned off.

The VPN client software (and all its components) are in
the "Exceptions" list, but still no good. I had a look at
the advanced settings and there was nothing obvious
there. Would it simply be a matter of opening a new port
on my laptop i.e. the same port that the VPN uses on the
company firewall I am trying to access?

I mean, I know I could simply turn it off and leave it
off, but, because this laptop is for a co-worker, I'd
like to have the firewall turned on if possible.

Thanks

Steve

Cisco VPN client?
Under the transport tab for your particular connection, choose to use UDP
instead of TCP 443.

Thanks for the reply Shenan,

Sorry, probably should've said, it's actually a Netscreen
VPN client.

Your solution sounds nice and simple (I like simple) but
I cannot find the transport tab for any of my connections
(but I suspect that has more to do with me being a little
slow).

Couldn't I just add this UDP port and number to the
Windows Forewall Exceptions list?
