Hi everyone. I'll be first to admit I have little-to-no experience with Juniper devices. I'm a Cisco/SonicWALL guy usually.
Long story short - we just took over a new customer from an existing IT provider, they have a Juniper SSG-140 and RDP is wide open to their terminal server from the outside. First thing we did was fire up our RMM and saw over 100k failed logins to the terminal server - about 10k/day lately.
I just want to change the port for now to prevent this and work out a VPN solution with them later.
I want to pick a non-standard RDP port. See attached screenshot of current configuration for RDP.
I tried changing the source port to 3333 to 3333 for example on both TCP/UDP, but opening up an RDP session from the outside to their public IP:3333 doesn't work after making that change, and neither does leaving standard 3389 either.
How...
