Step 1. Get all your GM's IP's and save them in a notepad or something so you remember them.
Step 2. Log onto your router.
Step 3. Look for something along the lines of "Inbound Filter" for me it looks like this:
Step 4. Add in your GM's ip's one each per slot and switch "Deny" to "Allow" then click "Add" or something along the lines of that for example:
Step 5. Now you have to portforward SQL which is port 1433 and for inbound filter, this is important. Change inbound filter to the inbound filter you should have just made!
Step 6. Now you should be set, you have to restart some routers and all, but this seems to be the easiest way to do it, and this is how i've done so.
