We have bits flowing over IP tunnels, and observability:
bash-3.00# dladm create-iptun -T ipv4 -s 10.8.57.39 -d 129.148.174.103 iptun1
bash-3.00# ifconfig iptun1 plumb 11.0.0.1 11.0.0.2 up
bash-3.00# ifconfig iptun1
iptun1: flags=2010008d1<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST,IPv4,CoS> mtu
65515 index 3
inet tunnel src 10.8.57.39 tunnel dst 129.148.174.103
tunnel hop limit 60
inet 11.0.0.1 --> 11.0.0.2 netmask ff000000
bash-3.00# snoop -d iptun1 -V
Using device iptun1 (promiscuous mode)

And as an added bonus, ssh over the tunnel:
bash-3.00# ssh seb at 11.0.0.2
