Connecting to internal computers through the VPN

We have a SonicWall TZ 170 and the VPN authentication works well. I think I have the firewall rules setup to let pc anywhere and dameware access internal servers but I can't get them to connect. The internal IP scheme is 192.168.101.x and the NAT etc is turned on. I have also turned on the "Follow NAT and Firewall rules" in the VPN Policy section. I have had no luck connecting to the internal servers. The Logs don't indicate any thing either.
Anyone got some ideas to test or turn on?

Thanks

What OS are you using? Standard or Enchanced?

Once you connect via the VPN see if you can at least ping the internal pcs IP address (Make sure there is no software firewall enabled on either pcs).  

If you can then you know the VPN is working.  If you have no trouble pinging the pc with PcAnywhere then you should check to make sure you have the correct ports setup correctly in PcAnywhere on the host and remote pc.  

Also make sure check you security services.

Standard OS
no it doesn't ping but the firewall is set to ignore them. Should a ping respond even thought the firewall is set on?

You are connecting via VPN client right?  If so turn off "Follow NAT and Firewall rules".  If you are connecting through a VPN you do not need to create any firewall rules other than the ones for the VPN connectivity.

If you need to apply firewall rules to the VPN connection,
you will have to add rules for the ports you want to open.
I suggest you make them very specific from subnet to subnet instead of general rules.
