I have recently purchased four 2011UAS-2HnD Mikrotik wireless routers (all re-flashed to RouterOS v6.11). I like them very much except for the monumental task of configuring hairpin NAT with a dynamic WAN IP public address. All of them are working fine but the time I consumed in configuring hairpin NAT was magnitudes more than that required for an inexpensive Dlink or Cisco/Linksys from Walmart or DD-WRT router which has the hairpin natting built into the firmware. There is nothing to configure other than configuring port forwarding to the desired private IP address. What I want to accomplish is a way to simplify configuring hairpin NAT for future customers such that I don’t have to manually configure each and every hairpin for each and every computer I encounter that needs accessed inside/outside the office using the same “name.dyndns.org:port” address. Has anyone written a script that would perform hairpin natting on ALL inside private IP addresses (e.g. 192.168.88.0/24) and handle dynamic WAN IP so that it would make the Mikrotik router perform just like a Dlink or Linksys? It seems to me that Mikrotik should have provided a checkbox on the “Quick Set” page entitled “Hairpin Loopback”. Checking it would be all that is necessary.
