Local UDP port for IKE communication. By default the port of the socket backend is used, which is usually 500
. If port 500
is used, automatic IKE port floating to port 4500
is used to work around NAT issues.
Using a non-default local IKE port requires support from the socket backend in use (socket-dynamic).
StrongSwan default: 500
