I have Viasat Business Class service with a persistent IP. Am I able to access my modem remotely through the internet?
Here's a 'boiler-plate' answer....
Open port 8080
enable remote config using port 8080
Password your router
subscribe to a DDNS service so you can always reach it, unless your IP address is etched in stone.
If your IP address is absolutely fixed, go to your IP address and add the port 8080 to it... like this:
You should see your router as if you're in front of your computer, ready to log in.
