I purchased 2 wrv210 routers, had a VPN tunnel set up and working OK.
Had DDNS working OK, VPN tunnel working OK, no problem.
I had some problems, and needed to exchange the locations of the routers. So I proceeded to change settings.
When I changed the DDNS settings, the DDNS refused to ´´Enable´´. It always stays disabled.
I tried resetting factory default settings, then enabling DDNS, but the DDNS status remains disabled.
I tried resetting (hold reset button 30 seconds), then enabling DDNS, but DDNS status remains disabled.
I read a forum where someone had a linksys router (another model) with the same problem.
They found the solution by backing up the setting to a config file, then editing the config file in notepad, then restoring to the router.
But WRV210 config file is .BIN, I can´t edit it.
I restored a previous config file I had, and the DDNS is set up and enabled, but it is the wrong user name, etc. So I try to make changes, and the DDNS always gets disabled (DDNS status:disabled)
The forum suggested backing up the setting first thing, as soon as you get the router.
But for me it is too late. Is there any one who can send me a WRV210 config.bin file, with the settings saved from a factory default, where there was never any DDNS set up? Then I can restore from config.bin file, and enable the DDNS.
It seems the WRV210 lets you set up DDNS the first time OK, afterwards it does not accept any changes.
~My mistake was I should have backed up the router settings as soon as I bought the router.
Any suggestions from the experts?
my firmware is 1.17
I have this problem too.
