Nov 13, 2018 · Re: Allowing OpenVPN through ASA. TCP/443 is open on ACL (On ACL screenshot it shows only UDP/443/. As per your NAT command you had configured identity NAT, that is Both Real Host and Mapped Host as same (ext_OpenVPN). It should be the case.

Allowing Microsoft PPTP through Cisco ASA (PPTP Passthrough) The Microsoft Point to Point Tunneling Protocol (PPTP) is used to create a Virtual Private Network (VPN) between a PPTP client and server.

The situation of having VPN traffic entering and exiting the same ASA interface is called VPN Hairpinning (or “VPN on a stick”).
