Previously we had - Endpoint.input_tcp: which handled RST and then called intercept_tcp_syn with a default forwarding option (connect to (ip, port)) - Endpoint.intercept_tcp_syn: also used by services like the HTTP proxy The RST handling wasn't clear for the HTTP proxy etc, so rename intercept_tcp_syn to intercept_tcp and ensure it handles RST packets too.
