Problem with port forwarding. I've tried everything!

[Regulith]

I'm trying to forward the ports for Blockland with my new AT&T router. It's a 3800HDV.
I forwarded the ports for Blockland and set the settings for my TCP exactly as the guide on the Help board says. No matter what I do, my server is still dead. Is there something I forgot? Does anyone have this router and can tell me what to do? If you need more information, I can tell you what you need.

Help me please! I really want to host today.

For lack of edit:

I also have Trend Micro security. I believe I have it so it doesn't block Blockland, but if you also have Trend, I'd appreciate a guide about what to do there too.

Please help me, I really want to host.

Come on! I'm sorry for the quad post, but I need to know how to fix this! Can anyone please just help me so I can be on my way?

TCP

Try UDP.

I already did the UDP part, I just forgot to say it. I was talking about the "Network Connection Properties" part anyway there. :P

3800HGV.

Whoops! Typo.

Well, nevermind. I tried to host on my other computer and it worked, so it's all good.
