Description

Apologies if this is the wrong place for this but I couldn't see a better place to post it.

I am using the SocksDroid applications here: https://github.com/bndeff/socksdroid (It contains a precompiled version of tun2socks from about 4 years ago.)

I am simulating an environment where WWW access is blocked by blocking incoming UDP and TCP traffic to my device at the router. So by default, all connectivity is broken.

I then connect to my local SOCKS5 proxy on LAN using SocksDroid.

Most applications now work fine but some are failing.

If I specify a DNS server within my LAN then all applications work fine.

So it seems that some applications are routing their DNS queries over the proxy but some are not.

I tried running udpgw on the proxy server and configured tun2socks to use it but this did not resolve the issue (I verified UDP traffic is flowing in both directions).

I tried using a closed source proxy client instead (SuperProxy) and everything is working fine.

Any pointers here would be greatly appreciated.
