UDP + tun

[omddd]

Hello.

Is it possible to configure shadowsocks-rust so that its behavior resembles WireGuard?
That is:

1. the client–server link uses a fast UDP-based transport (not slow TCP),
2. a tun interface is created on the client into which you can route various kinds of traffic (TCP, UDP, ICMP, …).

I tried to run a UDP server like this:
ssserver -s "100.100.100.100:1000" -m "2022-blake3-chacha20-poly1305" -k "9s9ldAXfVpMRXzCQRovnLNJ+3Ni3OS8+oFR2LqhxYT8=" -u

and the client like this:
ip netns exec GATE_SS /home/eris/.cargo/bin/sslocal -s "100.100.100.100:1000" -m "2022-blake3-chacha20-poly1305" -k "9s9ldAXfVpMRXzCQRovnLNJ+3Ni3OS8+oFR2LqhxYT8=" --protocol tun --tun-interface-name tun0 --tun-interface-address "10.255.0.2/24" --tun-interface-destination "10.255.0.1/24" --outbound-bind-interface eth0 -U

I check the result with:
ping 10.255.0.1
The reply comes back too quickly, as if it were from the local network.
It seems the client–server connection is not actually being established.

Is it possible to achieve the desired behavior, and how can I do it?

No, it's not possible, because shadowsocks is a family of proxy protocols for TCP and UDP traffic, not a VPN protocol for IP packets like WireGuard is. If you are looking for a proxy-like protocol for obfuscating your WireGuard traffic, take a look at https://github.com/database64128/swgp-go.
