How to use GpsGate using web proxy
If the web proxy is the default proxy for the windows installation, you can add some lines to the following two files (make a backup first):
C:\GpsGateServer\IIS\web.config
C:\GpsGateServer\Franson NMEA Service\GpsGate.Service.exe.config
You can open the files using a text editor and paste the lines below right above the line that reads </configuration>
<system.net> <defaultProxy useDefaultCredentials="true" > </defaultProxy> </system.net>
Make sure that you don't paste anything extra by mistake.
Save the file, and restart the service from SiteAdmin -> Service ->
Start/Stop -> Action: Stop, then Start.
If the proxy is configured correctly, the service should then use this when trying to make external connections.
Here is an example of how the add proxy information:
