I Have 2 computers at my house, One I'm using a crappy free dial up service to test on my host computer.

I Can connect my client to my host router completely fine. I Can ping the router and the computers inside the newtowkr.

My main issue is Viewing my Host's Shared resorces.

With my host computer firewall off ( xp sp 2) I Can view the host's shared resorces.

With it on I Cannot.

For both computers ( USING IPSEC) I have ports ( All UDP) 88,500,4500 and 1701 entered in exceptions. IpFilter is set to Permit All on both.
On Both Computers ( Sense it's xp SP 2) and my client ( Not for testing perposes but in practical app it may apply ) I Have Nat-T registry entered in.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IPsec

Manual putting in

AssumeUDPEncapsulationContextOnSendRule with a value of 2.

I Just don't get it. I Can't find anything else that needs to be open for this to work.

What am I doing wrong?

I would love to leave the firewall off and just use the routers firewall. But this is for my boss's buisness and I can't persuade him to do that.

Here are a few trial runs.

Trial 1: Both Firewalls off.
Results: Connect to network And can view files.

Trail 2: Client firewall on, host off.
Result: Can connect to network and view files

Trial 3: Client and host firewall on
Result: Connect to network but Can't view files

Trial 3: Both firewalls on but disable IpFilter on Both
Result: Connect to network but can't view files

Trial 5: Both Firewalls on but in ipfilter I have Protocol 50 and 51 Permit only on both
Result: Connect to network but can't view files

Trial 6: Both firewall's on and both have ipfilter on with all Permit all
Result: connect to network but can't view files.
