I configured the VPN with an IPSEC third party client package. I can create the tunnel and I do have a connection but I can only ping the LAN ip of the Netgear router. I cannot access any computers on the LAN. I had first tried a test where I just plugged in a single PC configured with my 172 network and I could connect and map drives just fine. I then disconnected that PC and connected the Netgear LAN port to my switch on my main LAN with a crossover cable. Now I can only ping the Netgear router but no other PC on the LAN. I used the diagnostic tab on the netgear web tool and I can ping computers on the LAN by selecting to use the VPN tunnel. So I know the connection is fine.
