I have two Cisco RV325's successfully setup with a VPN. I can see/ping various devices on the remote side. When I go to try and connect via a browser to a known/working http server on the remote side, it connects, but won't load the page. Can't get the VoIP phone to work through the VPN either. Routing table looks fine, verified the LAN settings on the remote side matches the remote IP address range in the VPN tunnel (as I said, I can ping various devices). I ran nmap from a local machine on the remote subnet (through the VPN) and get a response from the various devices (small office, about 30 or so devices connected). It's only when I try to actually connect through http or the VoIP phone that it begins to fail. No connection for the phone and the http connection is really slow, then ultimately fails.
10.24.91.0/2 = RV325 local LAN
10.24.50.0/24 is the router we're behind locally. (I don't see how this can be a problem if the RV325 locally has an established VPN tunnel to the remote RV325)
192.168.1.x is the remote LAN.
