Has anyone else had this issue, I've raised it with opendns and also on the csf firewall website, so anyone else who does come across it knows what to do. But why are they port scanning in the first place? It says on the small bits of info I can find on their website, it is not port scans, they are answering requests at a different port or something, but who's making the requests, we didn't have this problem with the vps's? I've spent hours on the internet and can't really find an info, it surprises me that this isn't an issue which opendns have a page on their site about - info for webhosts?Ĭristiano (top guy!) in dedicated support added the ips to the csf allow list but within minutes it blocked it again! We've now tried them in the ignore list. ![]() If this cannot be done in the router, as. This isn't something which is widely spoken of. To simplify, add the OpenDNS Primary and secondary IP addresses in the router. Is this is the reason so many users of opendns have problems accessing some websites? I wonder how many web hosts just leave this ip blocked, not knowing that it is for opendns. You must have access to an inbox to accept the auto invite generated invitation. We support Duo (preferred), Okta, OneLogin, Ping Identity and Azure SSO. I wonder if when a host blocks opendns ip's anyone using opendns can't access any of the websites stored with that host?

A feature highly requested by users, now you can link your phone as one of up to four additional devices, the same as when you link with WhatsApp on web browsers, tablets and desktops. I thought this would be an issue to raise. Today, we’re improving our multi-device offering further by introducing the ability to use the same WhatsApp account on multiple phones. The port scanning uses port 53 dns port and UDP - random ports (which is what triggers the scanning) So you can understand why our firewall blocks the ip. The WAN IP now associated with that users personal account and any filtering policies that they had chosen to use since the OpenDNS updater on the users personal computer will report the public address of the NAT as belonging to their personal account. However, we wonder why so many requests are being sent to our servers. ![]() OpenDns is a very famous DNS service used by a lot of people, but not everybody knows that they also provide some filtering product for individuals. We researched further and found out they are not hackers, they are a reputable company. OpenDNS Updater is an extremely easy to use android app to perform dynamic IP updates on OpenDNS services. Our firewall thinks requests from opendns are port scans and blocks the ip address 208.67.222.222. Hi, we have received alot of port scans to our new dedicated web server.
