Firewall Rules

[ITWORX]

Hi, please can someone assist with issue getting firewall port forwarding to work. I am very new to OPNSENSE and have only used MikroTik and a few other platforms to date. Despite setting what I believe are correct cannot get traffic to pass and suspect something silly I am missing.

I setup OPNSENSE on old HP ML110 server box for testing and getting it up and running fairly simple, lan, wan, dhcp all running and web traffic running 100%.

I have tried to setup two rules:

RDP access using custom port on server changed from 3389 to 240 with restriction on source ip e.g. 41.75.4.223 with destination public ip 41.75.4.224. Ideally rule should only accept request from this source IP address on port 240 and direct to internal terminal server 192.168.168.240 running port 240 as RDP listening.

The 2nd rule is a simple accept from anywhere on port 25 for SMTP to internal mail server 192.168.168.245, again destination public up = 41.75.4.224

I have tried to ping public up 41.75.4.224 from external address and I don’t get a response, presume this is due to ping turned off. Public IP’s given are just examples for sake of discussion.

I have taken a screenshot of rules and hope that helps. thank forum is advance for any help for Newbie
