iptables -t nat -A OUTPUT -p tcp --dst <target-host> --dport <target-port> -j DNAT --to-destination <intercept-host>:<intercept-port>

openssl s_client -connect <target-host>:<target-port> -showcerts

copy the PortSwigger server CA cert into /etc/ssl/certs/trustedcerts/PortSwigger.pem

link it into /etc/ssl/certs/trustedcerts/ and /var/ssl/trustedcerts/ as <hash>.0

openssl x509 -hash -noout < PortSwigger.pem
