First off, this is on the Dev Edition (Sense) Lollipop release. Phone is S-off/bootloader unlocked, but I doubt that matters. I am using AFWall+ to manipulate the firewall (iptables) configuration.
The problem is USB tethering. DNS requests aren't getting through to the tethered device no matter what I do if iptables is configured. I checked the logs and they showed that process -11 (kernel) was blocked from sending UDP (DNS) to the tethered IP address. However, I specifically enabled the kernel, -12 (tethering DHCP & DNS), and root apps for good measure. Nothing.
However, it is JUST DNS. If I use an onboard terminal to nslookup the name, I can use the IP address from the tethered machine just fine. It appears that TCP isn't being blocked, just UDP. Further, local apps have no problem access the network in any way - it's just the USB tethered PC that is having trouble. I have not tried WiFi tethering yet.
I have tried my usual app, DroidWall, and now AFWall+, but neither can get it done. Something seems to have changed in Lollipop, because this used to work in KitKat.
Any ideas?
