Is this stopping you from downloading files? Normally Vuze should just work without any port forwarding.

But if you did set up port forwarding, you may try to use this URL to see if the port is open: https://www.grc.com/x/portprobe=48756

@casino The router doesn’t block anything with Access Control disabled. If you are trying to make Vuze work, you don’t need to do any port forwarding.

@casino This can’t be done on the router. To the router, images and text are the same over HTTPS – just a bunch of bytes.

It is possible to do what you wanted to do by an app or browser plug in. But I’m not aware of any product that actually does that.

If you white list skype.com, all URLs you listed should be passing.

What are the reasons for blocking when you look at the logs?

[support]

We can’t do this on the router. Since the Google pages are sent over HTTPS, the router cannot see the contents. As a result, it doesn’t know which page is fetching the images. Unless we break HTTPS encryption on the router. But we do’t sacrifice security for manageability.

The Bing thumbnails cannot be blocked on the router because they come from the same domain as the main page. The links to the thumbnails were created when the page was generated on the Bing server, which determines which domain to use for thumbnails.

@casino Embedded images (i.e., those with “data:image”) cannot be blocked by the router. Browser plugins can hide these.

Images from the same domain as the page itself cannot be blocked. If you block the domain, the main page will be blocked too.

@casino This is not a normal proxy site. It’s main purpose is not to act as a proxy to other sites. It only acted as a proxy to twitter for that one URL. So it’s more likely someone set it up for the sake of convenience. Such as, access Twitter from China, where Twitter is blocked.

Search for “alexa top 10 million” to download the list of top 1 million web sites ranked by alexa.com. Then you can find all pinterest sites from the list.

Alternatively, you can do DNS lookups for all pinterest domains by appending each TLD as suffix. Drop the ones that are reported as “Non-existing domain”. You’ll need to write a script to do this (or see if such a script is already available).

@casino Someone decided to proxy Twitter contents on that URL. Maybe the site owner put the proxy there for their own convenience, maybe some hacker hacked the site and set up a proxy there.

The only way to block proxies like this is to block the domain. OpenDNS should have blocked most of the proxies. When you see one that’s not blocked, put it in the “Blocked URLs” box in Access Control, and make a suggestion on community.opendns.com to categorize it as proxy/anonymizer.

If you are worried about the images on Twitter, you can block twimg.com. It’s a Twitter domain.

How did you find the site?

@casino “data:image/jpeg;base64,…” is embedded image, it’s part of the page, not a link. You can’t block them unless you block the page.

@nholzmann01 Thanks for the feedback! This will be fixed in the next update. Additionally, we’ll add Cloudflare to the list of DNS services to select from.

@casino I got those from Alexa top 1 million list.
