I'm having trouble setting up my watchguard xtm 21 with one to one nat. I've read all the manuals on the site and in the kb, and I think I've set it up correctly, but may be missing a policy. Once I set up the 1-1 nat, the server loses connectivity to the internet.
I have a block of statics from my ISP. I added the additional IPs in network -> configuration -> external -> secondary.
Then went to network -> nat -> 1-to-1 NAT -> single ip -> interface external, nat base the external static ip, real base the internal ip address.
Save the config file, and the server loses internet. Remove the 1 to 1 mapping and it gets internet back.
I think I'm missing a policy that allows internet traffic - but the manual is sketchy about this - and I'm new to watchguard... any help is appreciated.
Happy New Year and thanks in advance.
