Well here's the deal, I have a network with VPN connections to our remote locations. We have gas pumps at a few of those locations and currently we have to use a dial up modem to pull transaction data from the pumps. I am looking into setting up COM port to IP converters (I have a few currently) so that we can just pull the data through the VPN. I am using Lantronix UDS1100 devices and can connect two of them together in the same location network. I have one set up at the remote location and can get to it through a web browser to the config page but cannot connect the two devices. I am also looking into using Lantronix's CPR program (COM port redirector) to hit the location UDS directly and mount it as a com port but no luck. It is acting like there is a firewall in the way but I have opened the ports that it is looking for. My network is set up with a Sonicwall tz200 at the main location and a Sonicwall tz100 at the remote locations. Any ideas on what I can try to get this to work?
