Configure DDNS on router or NAS not both, the former is prefer.
As for FTP issue, what specific error did you encountered?
Use this site - www.canyouseeme.org to verify that the require port(s) are not block.
Thanks for answering!
(and sorry for my bad english)
Ok i have done the check on that site and i get:
Error: I could not see your service on 80.219.XXX.25 on port (21)
Reason: Connection timed out
When I ping that IP (or the domain given by dyndns.com) with the cmd it works.. no loss of pakeges..
could it be that I have to not only do a portforward rule but allsow a virtual server rule in the advanced section of my router
or do I need a rule with this ip further up? right now the router only has the local IP enterd in the rules.. the normal 192.and so on.
thanks again!
ps. I now made the settings on the router like you sugested and dsabled it on the NAS
