A tunnel interface example:

utun10: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1350 inet 10.10.0.6 --> 10.10.0.5 netmask 0xffffffff

The following parameters are specific to IP tunnel interfaces, gif(4):

tunnel src_addr dest_addr Configure the physical source and destination address for IP tunnel interfaces. The arguments src_addr and dest_addr are interpreted as the outer source/destination for the encapsulating IPv4/IPv6 header.
