Hi

I have the following problem. I bought a TL-WDR3600, and everything works flawless, except the FTP acces over the internet. I checked all the manuals, did everything that was said, and still have no luck with it.
LAN access works fine, and I enabled internet acces too. I set up dynDNS, and from local adress, I can acces the FTP by using the domain name as well as the internet adress. But using an other connection (the 3G of my phone for example) doesn't work at all. The dynDNS forwards to my ip adress, but nothing happens. The strange thing is, using the default 21 port didn't work at all thru the WAN adress of the router, only the local one. I tried port forwarding (I used a port that wasn't in use at all), and it made possible to reach FTP thru WAN adress, but from outer network it does nothing.

Can you help me to fix this problem?

Thanks in advance.
