(Soon to be gone) I had an existing Router connected via eth to the RUTX50 WAN port. This router is a broadband Very high-speed digital subscriber line (VDSL) router has its own gateway into the street Fibre via vdsl.
I used it for redundancy as I tested the features of Load Sharing and Failover on the RUTX50. This is now isolated completely from RUTX50, as of yesterday. Note the Rule I am trying to apply to the RUTX50 has worked perfectly on that vdsl router for years.
Now as I begin the transfer of the same rules to the RUTX50, but the issue is as described in the title above.
I reach the RUTX50 from SIM 1 connected to a mast 5km away in clear view. Signal Strength -60db(Excellent). (Download typically 300mb/s)
The gateway traffic arrives at the WAN via MOB1S1A1 with a typical IP range 92.40.197.xxx
Here is the overview of Port Forwards RDC rule (see below).
IPv4 tcp, udp
From any host in wan
Via IP 92.40.196.xxx at port 3389
IP 192.168.2.156, port 3389 in lan
If I look in the Rule External IP Address dropdown list, I see only LAN IP Addresses and -Custom- and Any.
Q. Should I also be able to see 92.40.197.xxx in that list?
Of course I tried 'Any' but nothing gets through to the LAN.
Assuming I have done things correctly, why does it fail?
PS I use DDNS to pinpoint the current IP as updated in Services > Dynamic DNS > myddns settings.
