iPad HTTP Proxy configuration

Hi, I always used "SSH Proxy"(from Codinn) with the "Allow other devices to use this proxy" option before trying Core Tunnel.
As far as I understand enabling "GatewayPorts" should allow my iPad to use the proxy but it seems connection is failing.
I only added dynamic forwarding:7072, but also tried Remote with empty Target and localhost:7072 as Target without success.

I'm pretty sure I'm missing something. Should I configure a different port for the remote to connect to? Thanks in advance.
