Greenside Posted July 5, 2019 Share Posted July 5, 2019 (edited) Smart DNS Proxy is a service that makes it easy to access geo-blocked services such as TV and streaming providers. It needs to know your internet IP address and keep it updated constantly in order to work properly and since (as most of us do) I have a Dynamic IP, one of the ways to do this is to use a DDNS service. AIS provides its own DDNS service (called THDDNS) to enable remote access via port forwarding but just using my host name didn't work at all so I tried the recommended No-IP DDNS provider. That caused a big problem in that NO-IP was updating my address wrongly about every ten minutes and I'm beginning to suspect that this has something to do with AIS and its implementation of Carrier Grade NAT. So..... Does anyone know how to make a THDDNS host name resolve to a public facing IP address? or Has anyone found a good DDNS service that actually works reliably with AIS Power Package (50/10)? By the way, I've been very impressed with SmartDNS Proxy's live chat support who spent over an hour sorting out the original problem the THDDNS hostname caused.

muratremix Posted July 7, 2019 Share Posted July 7, 2019 It won't work. AIS and 3BB does DNS Hijacking. Smart DNS proxies won't work. just go to icanhazip.com and you'll see your CGNAT public IP. 1 Link to comment Share on other sites More sharing options...

Greenside Posted July 7, 2019 Author Share Posted July 7, 2019 That might explain it. May I ask how you know this and if there is anything published that specifically says that AIS does this? Maybe that would help me sort something out with the SmartDNS Proxy people as it sounds like there is little point in me trying out other DDNS suppliers. They must have come across the problem before. I guess the THDDNS host bypasses the public IP and jumps directly to the private one that AIS has given me. Is that even possible?

muratremix Posted July 8, 2019 Share Posted July 8, 2019 Go to https://www.dnsleaktest.com/ test your dns, you will see AIS DNS no matter what dns you may enter to your router like 8.8.8.8 etc. DNS over TLS would work but AIS provided routers doesn't support DNS over TLS.

Greenside Posted July 8, 2019 Author Share Posted July 8, 2019 Something more to think about! I'm right in thinking that Transparent DNS Proxy is the same as the DNS hijackings that you referred to initially? If so, it looks like the SmartDNS Proxy servers that I am using don't leak - the advanced test shows OpenDNS, Cisco OpenDNS and Google all of which are in the two locations of the servers configured in my router. The fact that I can access overseas TV streaming content would seem to confirm that it's working OK. Just to confirm, I'm not concerned with privacy merely access (or I'd use a VPN). The goal is to keep my Public WAN IP monitored and updated on Smart DNS Proxy's system. There is a script that I can run by calling a page in my browser that will do an auto update, so at the moment I'm looking to see if I can schedule a repeating task to do that although I suspect there will be an issue if the computer goes to sleep.

marcusarelus Posted July 8, 2019 Share Posted July 8, 2019 I'm in Thailand with 3bb and use a VPN. I go to that leak site and get, Hello XX.XX.XXX.XX from Singapore, Singapore The x's are numbers Link to comment Share on other sites More sharing options...

Greenside Posted July 8, 2019 Author Share Posted July 8, 2019 Just to get back on track, I have established that SmartDNS Proxy does work (on my AIS package at least) but I don't think my two original questions have been answered: Does anyone know how to make an AIS THDDNS* host name resolve to a public facing IP address? or Has anyone found a good DDNS service that actually works reliably with AIS Power 4 Package (50/10)? *This is the DDNS that AIS provides to allow portforwarding Link to comment Share on other sites More sharing options...

I've also noticed it leak DNS from openvpn sometimes. 2 out of 3 times it shows AIS in DNS. Link to comment Share on other sites More sharing options...

Inside Thailand I'm seeing 115/101 AIS CM to AWN BKK and similar to AIS in CM but anything outside SEA is at a crawl: Manchester and London UK are 21/2 (that's not a typo!). Speeds the same with or without SmartDNS Proxy. I have noticed that streaming iPlayer has been very poor in the last day or so but for my limited use I don't feel it's worth upgrading from 600 to 100 per month. Thanks for explaining the impossibility of getting a Public IP from the THDDNS hostname. For the moment, I'm running the API script in Chrome using Task Scheduler. It's not an ideal solution but it does update the IP regularly. All my questions addressed now - thanks to all who contributed. Link to comment Share on other sites More sharing options...
Greenside Posted July 9, 2019 Author Share Posted July 9, 2019 It seems that AIS just gave us an unannounced speed upgrade to 100/50 for the same price of 599 + VAT. Neat ???? Link to comment Share on other sites More sharing options...
