Cisco VPN and Port Forward Issue

All,
I have a Cisco PIX I have setup for VPN and Port Forwarding. I am forwarding two ports, web server and terminal services, to a server on the internal network. My problem is when I attempt to access terminal server or web server of that server while connected to VPN, I am unable to to connect.

Is it possible to connect to those ports if I am forwarding from my public IP address also?

Thanks,
Tareef

Are you trying to access these by their public IP that you have static xlates for?
Are you using IP address or DNS name?
Yes, it should be possible to access those ports through the VPN even though you have static nat.
Are you using a different IP subnet for your clients than the inside network?
Can you access anything else on the network while connected via VPN?
Do you have any access-groups assigned to the inside interface?
Do you have split-tunneling enabled?

Here is my acl:

access-list inside_outbound_nat0_acl permit ip any 192.168.3.0 255.255.255.0
access-list outside_cryptomap_dyn_40 permit ip any 192.168.3.0 255.255.255.0
access-list 103 permit icmp any any
access-list splitvpn permit ip 192.168.0.0 255.255.255.0 192.168.1.0 255.255.255.224
access-list splitvpn permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.224

None of those will be applied to the inside interface...

Hint: don't use "any" in the vpn specific acls. Assuming inside lan is 192.168.1.0 and VPN client pool is 192.168.3.0:

access-list inside_outbound_nat0_acl permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0
access-list outside_cryptomap_dyn_40 permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0
