20.1 Legacy Series / Can't redirect TCP/UDP traffic to socks5 transparent proxy?
« on: April 13, 2020, 05:51:11 am »
像redsocks、ss-redir（shadowsocks）、clash等客户端可以开启一个socks5的透明代理。在LEDE、linux平台上，可以通过IPtables将流量重定向到这个socks5透明代理端口。比如我可以把所有访问YouTube的流量重定向到这个端口。但是在opnsense上设置了端口转发规则后并不能生效。我可以转发流量到另一个http端口，也可以转发流量到squid的http透明代理，但是当我转发到一个socks5的透明代理时，没有任何事情发生。
Clients like redsocks, ss-redir (shadowsocks), clash, etc. can open a socks5 transparent proxy. On LEDE and Linux platforms, traffic can be redirected to this socks5 transparent proxy port through IPtables. For example, I can redirect all traffic to YouTube to this port. However, the port forwarding rule set on opnsense does not take effect. I can forward traffic to another http port, or I can forward traffic to Squid's http transparent proxy, but when I forward to a socks5 transparent proxy, nothing happens.
