Our office uses a netgear FVS318 Firewall/Router. One of the Dr's offices in the building wants to set up their own private VPN. When they initially set up their connection it worked fine but recently stopped working. I was asked to make sure that ports 1723, 500, 47 are open on the firewall. In the FVS I went to add service, and added the port # and protocol. This is exactly how Netgear says to open these ports. Am I missing or forgetting something here?
I have saved screenshots in the firewall config options here:
Also, is their a simple way to test if these ports are actually open or not? Thanks!
