This page can be used to enable/disable IPsec, you may also specify whether NAT-Traversal should
be used.
NAT-Traversal is mainly used for connections which traverse a path where a router modifies the IP
address/port of packets. It encapsulates packets in UDP and therefore requires a slight overhead
which has to be taken into account when running over small-sized MTU interfaces.
Please note that running NAT-Traversal makes IKE using UDP port 4500 rather than 500 which has to
be taken into account when setting up firewall rules.
