If your running 12.2.5T you can set up a one to one esp nat translation that will allow one of your 2 clients to connect to the pix without the additional public ip's. As a result, IPsec Encapsulating Security Payload (ESP) will only pass through a NAT unimpeded if TCP/UDP protocols are not involved (as in IPsec tunnel mode or IPsec protected GRE), or checksums are not calculated (as is possible with IPv4 UDP). As described in [RFC793], TCP checksum calculation and verification is required in IPv4. El IPSec sobre el TCP trabaja con el cliente del software VPN y el VPN 3002 Hardware Client.

PPTP can be easily blocked by restricting the GRE protocol. IKEv2 uses UDP 500 for the initial key exchange, protocol 50 for the IPSEC encrypted data (ESP) and UDP 4500 for NAT traversal. IKEv2 is easier to block than OpenVPN due to its reliance on fixed protocols and ports. 26/06/2012 My VPN provider gives me the option between using UDP and TCP for connections.

UDP stands for User Datagram Protocol. Though it can be configured to run on any port, OpenVPN runs best on a UDP port. Unlike UDP, TCP carefully checks whether data is received by the recipient in the correct form and order and can request it again.
