m0n0wall Forum - Problem with domain to webserver...

My problem is:
Within my LAN I can reach my webserver with example.com and with www.example.com and all my sub.example.com.
But from WAN I can't reach my webserver with example.com but with all the otherones.

This problem happend some days ago, and before it have worked for over a year with no problems. I am not sure, but this problem could started when I upgraded my m0n0wall from 1.233 to 1.235. But I'm not sure it was right then because I discovered the problem 2 days after when I was trying to reach my website from work. I havn't changed any settings on my m0n0wall for months.

And something else I can say is that before i could reach my m0n0wall from WAN by https://domain.com:port but after this happend it don't work anymore, I have to use https://host-name-of-m0n0wall.domain.com:port to login.

I tried to change back to m0n0wall 1.233 with the webgui firmware update, but it did not work, then i tried to upgrade to 1.3b18 and with the same result.

So all worked fine with 1.233 it seems and with newer firmware it dosen't. Is it any thing new that are changed after 1.233 that makes this happend, or thoose somebody have any idea to do to get this to work again??? Or is that something else that may cause this problem?

Some settings that maybe will be useful.
