Hairpin NAT and DNS

[pomah]

Hi guys I’m using the follwoing dns script to update my IP:

/tool fetch address=“freedns.afraid.org” host=“freedns.afraid.org” mode=http src-path=“dynamic/update.php?mycode” keep-result=no

This works great, now I would like to setup hairpin NAT on my network, so that I can use the DNS inside and outside of my network, how do I move forward?

I can also add that I have moved my wan IP server to a new bridge, called bridgewan, so that ethernet1 and ethernet5 is bridge to my ISP directly.

Any ideas?

Create a NAT rule that looks like
/ip firewall nat
add chain=srcnat action=masquerade src-address= dst-address= out-interface=

This does nothing for me…

How can I debug this?

Can you please share your firewall filter and NAT rules with us.
Also give a brief overview of your devices involved.

Hi could you be of help to explain to me how “print” those for me to share with you all?

As for devices in my network I have 2 laptops, 2 cellphones, 1 server, 1 htpc, 1 tv box.

I have a dns setup so that I can allways reach my server, but everytime I get home I need to use the interal IP, everytime I’m out I need to use the external IP, I would like to make sure that I can allways use the external one with the help of Hairpin NAT, but I cant get that to work properly.

Thanks for helping out.
