I want all traffic on the guest Wi-Fi to go through a SOCKS5 proxy

I was tried Tor modifacation and SOCKS Clients (proxychains-ng, redsocks)

Tor ignores Socks5Proxy settings.
proxychains-ng works manually (proxychains4 curl -L https://ifconfig.me shows the proxy IP), but doesn't force all traffic from br-guest through the proxy.

What is the best way to force all Wi-Fi guest traffic (br-guest) through a SOCKS5 proxy?
