Since no one would bother to answer this poor wi-fi reject, *sighs* guess I'll try again...
I found out that is a point 0 to TCP/UDP.
Maybe you didn't open all ports, and maybe trading isn't possible in your case because all the TCP/UDP ports were not opened before the trade attempt. It wouldn't hurt to try the TCP/UDP opening act again, this time, opening port 0 of both TCP and UDP concurrently with ports 1 to 65535, meaning, rather than leaving even one port closed by opening only ports 1 to 65535 while leaving out port 0 from the range of ports being opened, open one more port than than the number of ports from 1 to 65535, meaning the range of ports to be opened is amounted to: 0 to 65535(in BOTH TCP and UDP)...
If it still won't work, try asking an all-around wi-fi-tech-specialist web site forum, as I witnessed, like it or not, at least in my opinion, that very few members browse through sppf tech forums to help others who have wi-fi problems on any device(not just DS/3DS's, but including PC/Mac, Xbox, Playstation, etc.) compared to all-around wi-fi-tech-specialist web site forums more popular in tech support areas than pokemon-specialist sites like serebii and/or sppf... If speed in any area not in the site's specialty doesn't help you here, maybe it will elsewhere, most likely in a place that specializes in answering people's wi-fi or computer problems, which may be within the scope of what you're asking... Whatever you plan on doing when it seems no one will help you in one place, there's always other places that could help you. Don't give up looking if you don't get an answer quickly in one place...
