What you have created sounds right. Sorry if some of these questions sound basic.
Are you testing from inside your network or from outside (these need different rule sets)?
I've tested from both, neither works
Have you placed the port forward rules at the top of your rule list (to ensure we don't have any interfering rules)?
yes, still same issue
Do you see any relevant traffic in your logs on your DFL or server?
nothing relating to an RDP connection appears in logs
Does you server have any firewall rules in place that could be interfering?
no, server answers without issue on previous router and on LAN...have same problem trying to go to Win7 workstations, ran tests on different workstations, ports, etc., same problem, no answer
Does your server have the DFL as their default gateway?
yes
Spoke with DLink support also, they had no answer other than doing hard reset.
