I am trying to set up a DNS proxy for friends on VF VDSL. I can't change the Android wi-fi to a static IP address. Is this possible with VF or does a static address have to be specially requested? I can change it on the router, but would rather not have to since tenants are fed from that.

Replace the router (Draytek bridged to a Mikrotik maybe) with something that can be configured to do what you wish or build your own DHCP/DNS server (R Pi or ODroid maybe) and use the DNS server to forward traffic according.

I'm not sure what Voda have to do with it.

It is a router supplied by Vodafone so I guess they have at least that much to do with it. I'm trying to set this up today at the person's address. Is there any way to work around this that doesn't involve changing the router?

Can you please explain what you mean by a "DNS proxy"? I'm not sure you are using the term in its conventional sense.

I think you might be meaning you want to set the router to hand out geo unblock / smart DNS resolver IP but only to certain devices? I don't think that can be easily achieved with an ISP router such as HG659 or VF Ultra Hub.

This was my understanding.

At which case, router doesn't matter just entering the settings correctly in the device.

Watchout for apps that hardcode dns servers to avoid 'unblockers'

You could also add NAT rules to redirect all DNS traffic to a particular IP, but again not something easily done on ISP supplied routers such as the HG659 or Ultra Hub.

I haven't used the latest Android but aren't manually specified IP / DNS addresses tied to SSID profile? So you shouldn't have any trouble assigning static DNS to individual devices that need 'unblocking'.

OK, it's getting over my head now. I just want to tell the Android box to use DNS4ME instead of the default DNS server. If I can't do that, then I have to change the DNS server setting in the VF router, which I can do but would rather avoid. But when I try to change the setting in the Android device, I can only do it if I change from DHCP to Static IP. But when I tried to do that, the Android box greyed out the setting to accept the change and would only let me cancel. I can't change the DNS server unless I switch from DHCP to Static, but it won't let me do that. I am assuming (without knowing) that this has to do with the VF router.

Yep buy a little baby Mikrotik.

Set an IP address on either a bridge or single interface in your router's subnet.

Google a script for a Dynamic DNS server of your choice (no-ip would be mine, can share a script ive used for friends). Set a route in the mikrotik so it knows how to access the internet.

Set your unblocker's DNS servers in the Mikrotik

Go to your VF router, in DHCP settings, tell the DHCP server to give clients the IP address of the new mikrotik for their DNS server.

The mikrotik now acts as the DNS server for your network, plus it will update your IP with your domain, which you can then use with your unblocking service (or maybe your unblocking service has a direct way to update IP with it - eg. http post)

I can remember coming across something like that in an older version of Android where the 'Save' is greyed out even after inputting valid static IP / DNS addresses and values. Pretty sure it is a bug in Android, if I remember correctly you just have to 'forget' and add the network again. It does not have anything to do with VF or their supplied router.

Thanks. I have gone through that several times for other reasons because I lose the connection after changing DHCP/Static so I have to forget and then re-establish the connection. It didn't seem to make a difference for my issue but I will try again with that in mind.

Try installing the DNS Changer app. If it is compatible with the device.

Set the static up address of your android box to something outside the range of the DHCP range that’s configured in the VF router. e.g. if DHCP range is 192.168.1.100-192.168.1.254, set up the up address of your android box to 192.168.1.2. (Be sure to not use the LAN address of the VF router!) Then reboot your VF router to remove the previous address assigned to your android box. This should stop you losing your connection.

What Android device are you trying to configure? Is it rooted?

Not sure about S7., but additional VPN & DNS options can be found under "More Networks" on Galaxy S3/S4/S5.

I finally got this working on my identical device at home so I should be able to do the same the next time I am at my friend's place. I just wasn't going far enough into the settings. As a temporary fix, I changed the setting in the router but can put that back on my next visit. Thanks everyone for the help.

Another question: I believe my friend has been upgraded to VDSN and IP allocation is now dynamic. I remember reading something about this awhile ago. Does he need to request a static IP from VF in order to be able to use an external DNS server?
