Can't reach external IP from LAN

[eXtremer]

Hi all.

So, I have a mail server, I can reach it from my LAN when I use the private IP (192.168.0.222) but when I use the public IP (87.226.61.X) from my LAN I can’t reach it, why ? I’ve just change from d-link router to mikrotik and I didn’t have this problem with d-link.
What I’m doing wrong ? Please help.
Tahnk you in advance.

Note that the same issue occurred with the D-Link - it just decided to not give you any options and implement SOME NAT rule that fixes it for you without telling you. RouterOS requires you to configure everything manually - which can be both a blessing and a burden. Mostly a blessing, though.

I’m using winbox, not to good with the console, tried the example but is now working, don’t know what I’m doing wrong…
Maybe smb could help me with the right code ? Thank you.

Mail External IP: 87.226.61.X
Mail Internal IP: 192.168.0.222
LAN: 192.168.0.1/24

Winbox tasks are 1:1 to the command line.

/ip address add address=1.1.1.1/24 interface=wan

means click on the IP button, click on the address button, click the + field to add an entry, set the address field to 1.1.1.1/24, and set the interface field to “wan”.
