Let's start this right. I am not experienced with routers at all. I am setting up a network to use terminal services for point of sale software on a file server at "headquarters". 3 stores total. All using RV042 with 1.3.3 firmware. VPN between 2 locations on United Telecom using static IP stays up forever and a day. VPN between first location and another on SBC DHCP goes down temporarily in random patterns, anywhere from 2 seconds to 5-10 minutes, half an hour apart, and hour apart... completely random. If I forward RDP port in to the server, and delete the tunnel to the DHCP location, remote desktop stays up indefinitely (over internet, not tunnel), but has limited access to local printers on the DHCP location as those ports (printers) are only visible through the remote desktop. Not to mention that the traffic is no longer secure. Using dyndns, aggressive mode, keep alive, etc. Have gone around in circles with tech support ppl at all involved companies, and have been given no helpful information. BTW, if I leave a remote desktop up even after disconnect, it will reconnect as soon as the remote secure IP's become visible again. And when the tunnel is down, internet connectivity is down as well. I have also set up a varying (test) tunnel with the current DHCP IP set as Static IP only... same results as with DHCP+FQDN. The connection is there unattended, and always resets itself, but we cannot afford to have it go down right as we're printing a receipt. Is this an issue with the DHCP ISP, or with the router? Next step is to try the DHCP location to the secondary location, but the 2 IP's on telecom are a digit apart.
