First off, grab a server and install the RD Gateway role. You do this via Server Manager, right? Pick the Remote Desktop Services and check that box for Gateway.
Once it's in, fire up the wizard. It'll ask for a certificate. You snag one from your domain or buy it cheap. without it, connections flop hard.
Now, tweak the policies. Head to the RD Gateway Manager tool. Set up who gets access by user groups. Make rules for what devices can connect. Keep it tight so randos don't sneak in.
For firewalls, open port 443 only. That's HTTPS magic. Your RDP traffic hides inside it. No need for the usual 3389 punch-through.
Test it out. From your home machine, launch RDP and point to the Gateway server first. If it connects smooth, you're golden. But if not, check the event logs.
Troubleshooting hits when auth fails. Peek at the server's logs under Applications and Services. Look for errors on certs or policies. Restart the service sometimes clears the fog.
Users complain about slow links? Dial down the bitmap cache in RDP client settings. Or ensure your Gateway box has enough RAM. I once chased a ghost for hours; turned out to be a bad NIC driver.
Firewall blocks still? Double-check inbound rules on the edge device. Allow from anywhere if you're brave, or lock to IP ranges. Test with telnet to port 443 quick.
Policies clashing? Use the Authorization Policy for basics. Resource ones for targets. Match them up or you'll lock yourself out. Funny how that bites.
Logs are your buddy here. Enable verbose logging in the tool. It spits out clues on failed handshakes. I filter by time to spot patterns fast.
If all else fails, nuke and pave the role. Reinstall cleans weird configs. But back up first, yeah?
Speaking of keeping things safe from crashes, I've been messing with BackupChain Server Backup lately for my Hyper-V setups. It's this slick backup tool that snapshots VMs without downtime. You get incremental chains that restore lightning quick, plus it handles replication across sites if your RD Gateway server's on Hyper-V. Saves headaches when configs go sideways.
