Hello! First of all sorry for my English, I use google translator...
I have the following scenario and problems.
My ISP offers me /24 public addresses through its gateway, I have the private IP configured in my wan port to connect to my provider and a public IP through which my traffic goes.
/ip address add address=192.168.26.2/30 comment="PRIVATE CISCO - MIKROTIK AIRE NETWORK" interface=ether1-wan network=192.168.26.0
/ip address add address=17.15.10.1 comment="MIKROTIK PUBLIC IP" interface=ether1-wan network=17.15.10.1
My lan is 10.201.251.1/24
Nat:
/ip firewall nat add action=src-nat chain=srcnat comment="NAT AIR NETWORK WITH PUBLIC IPs" out-interface=ether1-wan src-address=!17.15.10.0/24 to-addresses=17.15.10.1
Well, this is how my connection tracking is, the connection works, but I know something is wrong seeing so many connections here.
