SOCKS5 proxy using a specific network interface

Question

I want to create a SOCKS5 proxy using a specific network interface. The reason is that I want to use Chrome using a specific network interface, but I can only set up a proxy in Chrome.

I created a SOCKS5 proxy by goproxy

proxy socks -t tcp -p '127.0.0.1:1080'

Although the manual says it can bind to a specific network interface, I was unable to do so.

Any other simple solution is welcome. I just need to create 127.0.0.1:1080 proxy redirecting the traffic from tun1.
