Error Code: 86420

OK, so my DSi keeps giving me this error code every time I try to trade with someone in the Pokemon Wi-Fi Club. It's getting VERY frustrating because all I want to do is trade a Pokemon... I looked at support.nintendo.com, and they say it could be firewall. Well, I tried tinkering with that and nothing happened. I don't know what else to do. Has anyone had similar problems? Any help will be appreciated. Thanks. :)
 
OK...

Since you already tried firewall adjustments:

Nintendo.com Support said:
... 2. If the problem still persists with the firewall off, you may need to open ports on your router through the Port Forwarding feature.
1. Create a manual connection on your Nintendo DS and assign a static IP Address.
2. Open ports 1 through 65535 as both TCP and UDP.
3. Ensure the ports are forwarded to the same IP Address given to the Nintendo DS system during the manual setup.

Trouble connecting to a friend?
If the above steps have not resolved the issue and you are trying to connect with specific friends, the problem could potentially be an issue on your friend's network. Your friend will have to perform these troubleshooting steps with their home network.

Yeah, I saw that and was like, "Open ports 1 through 65535... TCP and UDP?" Lol I have no clue how to do that or what that means. I created a manual connection and that worked, and I tried trading with someone else and it also worked. I don't know if it was the connection or the person, but I'm going to try it again and see if I'm still successful. Thanks for your help!
