I bought this router 1 month ago and it worked until today.
Now I can not connect from external network through router to FTP server behind it.
Clients get an "Invalid port command." message.
Tried to reflash firmware->reset router->reconfig manually... same problem.
It seems router does not translate PORT commands right.
(Latest firmware.)
Change to another router everything is working fine again. Someone experienced same bug? Is there any solution?
(Maybe I will ask refund if it can not be resolvable. I thought Cisco is manufacturing quality products. Am I wrong?)
