hi, i am using a a RV082 with my DynDNS Account. but the DDNS Update won't work. on Setup/DDNS the router writes for about 1-2 minutes: 'Updating...' and later: 'DDNS server is currently closed.' the DynDNS account is valid and active. with the same Broadband connection an WRV54G Router DDNS works fine. does anybody know something? the routers firmware: 18.104.22.168 (the latest i can find) thanks!
