Hello,
Some of the firewall rules are based on WAN address which is dynamic. How to make firewall rule to read it and use current, because now I enter it manually and if it changes I should change all rules that uses it.
You have to write a script which periodically checks DNS and canges Ip address accordingly.
Here is an example:

You can also get around having to use an IP address in many rules by using in-interface and out-interface, and knowing what chain the packet should be in at what time during processing.
Thank you very much ! I think scripting would be the best choice for me.
