Or you have a firewall up.

But I can't tell what's wrong since you didn't supply any IP PLAN for me to look over. Since many will not tell such the discussion dies instantly and the poster is left to call in onsite help.

Next time, reveal the firewall settings a bit of the IP PLAN and forget port triggers. Just port forward. And again, you didn't tell what ports you forwarded. All you didn't tell... matters.
