Code improvement

• Use an existing config format instead of rolling a custom one (e.g. INI).

• Implement reading from standard wireguard configuation

• Instead of passing around a config map[string]string everywhere, parse the config once, at the top of main, and then pass properly-typed arguments to the functions that need them. For example, tcpServerRoutine should just take an int.

• Listen for Ctrl-C at the end of main so you can shutdown gracefully. (unnecessary, sockets are closed automatically upon shutdown, and wireguard peers do not need to be notified of shutdowns)

• Use io.Copy (or io.CopyBuffer) to simplify connForward

Maybe make it semi-compatible with wireguard configuation

Came here to an open issue for that specifically. SelfSecretKey, SelfSecretKey, SelfEndpoint, PeerPublicKey, PeerEndpoint & DNS can just be directly read from the PrivateKey, Address, DNS, PublicKey, AllowedIPs & Endpoint of a wg-quick config file directly. Being able to supply the config using 1 config key like WGConfig = .../some/path/wg_quick.conf and/or -wg-config .../some/path/wg_quick.conf as command-line argument would be ideal

It 's very helpful to read the values from the wgcf config file.
