XP Firewall and Router based VPN

[EA_AB]

I'm having a problem with XP's firewall. I have 2 netscreen routers
with a VPN connection between them. I can access the hard drive
content when I turn off windows XP's firewall but when I turn it back
on I cannot. I've opened about a dozen ports 500,4500,47-51,1723 etc
anything I could google up. Still nothing. I've contacted my routers
technical support and spoke to a level 2 tech who suggested I just turn
off windows XP's firewall because it wasnt ment for 'prime time'.

Any help would be greatly appreciated. Just to make things clear: I'm
not using a client based VPN solution. The VPN connections exist
router to router and its working fine without XP's firewall on.

Thank you

Eric

Create a XP SP2 firewall exception for "File/printer sharing" and 'Peer
to Peer."

to Peer."

I've added the Peer to Peer to my firewall exceptions. the
File/printer sharing was already in place. I've looked at my
pfirewall.log and my traffic is being dropped at 445 and 139. I've
tried to add those ports to the exception list manually but it gives a
error that the ports already exist. I've tried the netsh command line
for 445 and 139 and they are still being dropped.

Any thoughts?
