Hi,

Probably a known issue: my Sonicwall tz100 blocks Netflix. I m sure of that since on my Iphone I can t access it on my local network/wifi but I can via mobile network/3G.
If I surf on any device in my local network to netflix.com it just says that it is unavailable. Other sites are perfectly reachable.

Pls advise.

I don't have any paying services so contentfiltering isn't active.

Does the router belong to you or your ISP?

If yours, what make/model is it.

If the ISP, contact them to make the changes.

Seems to be a dns issue.

To test if dns, on a pc change the dns setting to use google dns.

If you are not familiar with how to do that see:

If it works, then why not just leave it set that way. If it does not, then it can't be a dns issue, but rather something in the router.

Probably a dns issue on my internal network, a forward of my local dns that does not work correctly. For the time being it works with google dns. So I leave it that way.
