Hi, I`m new to Mikrotik and got some problems with forwarding http traffice to my webserver. I have set up a few NAT`s in the firewall setting for outgoing traffice before, som I am familiar with the setting.

The problem appears when I trie to NAT WAN-access to my webserver at the LAN side. I`ve set up NAT, and gain access from WAN to my server, but when the rule is active (as nr 0) I´m not able to access webpages at the WAN side from my computer.

Do I allso need to garant LAN access to WAN when NAT on port 80 is active?

Your nat rule must be dstnat for all the traffic with destination your wan ip.. If you dont use your wan ip as destination you get problems like this..

Solved, thank you!

If you have a dynamic WAN IP address you can also qualify the rule with 'in-interface=WAN connection-state=new' instead of the WAN IP. Same effect, slightly more expensive but less maintenance required.

Karma vote pleasee!

Thanks!
