Improved version of the tun2socks

[kayrus]

I made a couple of improvements in my fork: https://github.com/kayrus/go-tun2socks

• An ability to manage tun routes including automatic hostnames resolving
• Switch to go-wireguard TUN driver for a better windows support
• Support custom MTU setting

@eycorsican I'm not aware about the current project vision and a roadmap, therefore I'd like to get your opinion on whether it is feasible to merge my changes to your branch.

@kayrus your version of tun2socks works great on windows 10, but your code doesn't set the DNS server on the tun interface making the tunDns parameter useless. Could you fix it :-)

[kayrus]

I haven't tried the DNS feature yet even in *nix OS. I'm using SSH socks, which, I guess, doesn't support UDP. Can you suggest a Linux SOCKS5 server, which handles UDP?

@kayrus
The -tunDns and -tunGw parameters are not working. Default gateway and DNS servers Is not set on the Windows wintun interface.

[kayrus]

@steom yes, I know. I need more time to fix this.

[kayrus]

I brought back DNS support for windows. It may also work with linux/macos. Please test.

[steom]

the dns is configured now
but ip, subnet, and gateway no.

but after manually add the value:

panic: runtime error: slice bounds out of range [:1500] with capacity 1300

but ip, subnet, and gateway no

that is weird. in my case IP addresses are configured correctly.

panic: runtime error: slice bounds out of range [:1500] with capacity 1300

which parameters did you use for the CLI? I suppose I forgot to set MTU size inside the core/lwip.go. I need to reuse the MTU argument and bypass it core/lwip.go init function.

[steom]

Command line used:
-exclude -proxyserver -tunaddr -tundns -tungw -tunmask
In Windows net interface only dns Is set, ip subnet and gateway Is blank

[kayrus]

@steom I made an MTU fix in my fork master branch, can you try to reproduce the panic once again?

[steom]

I Need the new binary

[kayrus]

-exclude -proxyserver -tunaddr -tundns -tungw -tunmask

please provide all arguments, including their values. Usually it is not necessary to specify the tunGw and tunAddr, because they are taken from defaults.

[kayrus]

@steom I'll make a new release soon.

proxyserver 10.0.0.100:1080 -tunaddr 192.168.0.2 -tundns 1.1.1.1 -tungw 192.168.0.1 -tunmask 255.255.255.0
