I’m new to Mikrotik devices having used Cisco devices for quite a few years. I’m liking the flexbility of Mikrotik J
I am trying to port map the same external IP address but with different ports going to different internal addresses. When I compare what they say on this forum and other sites it looks the same but one of my ports works and another doesn’t.
Here’s my setup:
External IP range: 123.123.123.176/28
Internal IP range: 10.10.0.0/16
I have a text externally available machine on 123.123.123.183. I can currently receive UDP requests on 1194 (to internal IP 10.10.1.16) without any issues. I have set up TCP ports on 12000 (to internal IP 10.10.1.224) and 12001 (to internal IP 10.10.1.16). I have netcat listening on those ports as a test, but telnetting to either of those using the external IP from other hosts times out.
I am probably doing something really stupid, so sorry for my noob knowledge! I am running RouterOS 6.38 by the way.
Thank you
