Question : Problem: Gateway to Gateway VPN One-Way Shared Folder Access

I have a gateway to gateway VPN setup using two Linksys RV042 routers. Netbios boardcast is not enabled. We used a WINS server for name resolution on the network (it's on network one).

First Network:
192.168.3.XXX
255.255.255.0

Second Network:
192.168.5.XXX
255.255.255.0

Both networks can ping each other fine.
Second network can access shared folders on first network, but first network cannot access shared folders on Second network. What's going on?

Answer : Problem: Gateway to Gateway VPN One-Way Shared Folder Access

Users can create exceptions in the firewall configuration if you like, but they cannot switch it off.
As mentioned the firewall creates an exception for file and print sharing when it is enabled, but only for the local LAN. If you want to go the exception route you can do so by going to control panel | windows firewall | Exceptions | highlight file and print sharing and chose edit | highlight each protocol/port ( all 4 one at a time) and chose change scope | add your remote VPN subnet or "allow all computers" | save

If you want to disable the firewall, open the group policy management console on the SBS to group policy objects, and disable (not delete) the 2 polices, by right clicking on the policy and choosing GPO status and un-check enabled:
  Small Business Server Internet Connection Firewall
  Small Business Server Windows Firewall

It can take up to 90 minutes for the policy to be applied to the workstation. You can force this almost immediately by running at a command line, on the workstation:
gpupdate /force
