Try it without +ip. Your real IP will come up when in DMZ. If it does not and still have problem use +ip <your real outside ip> and box in DMZ in all cases. ALLOW IN on 27015/UDP from ANYWHERE. With this much trouble I would not use +ip or +port at all until this is sorted.

Settings like this:
max_queries_sec 1
max_queries_sec_global 1
max_queries_window 1

That alone will 'hose' HLDS from appearing on the list. Those settings should have never been touched.

If one cannot figure it there comes a time to start over.
