This returns no output.

Oops. I guess I have to fix my config file. Or is this because I'm on Solaris 
10?

So what can I do to protect my traffic against it?

Nope, this is IPsec between Solaris 10 1/06 i86pc and Solaris 9 12/03 sparc (:-)

This is on my proof of concept config with no NAT, looks like I'm using AH + 
ESP:

ip.tun0: flags=11008d1<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST,ROUTER,IPv4> mtu 
1395 index 3
        inet tunnel src ###.###.###.### tunnel dst ###.###.###.###
        tunnel security settings  ah (hmac-sha1)  esp (3des-cbc/<any-none>)
        tunnel hop limit 60 
        inet ###.###.###.### --> ###.###.###.### netmask ffff0000

That is correct. The ADSL "modem" has two interfaces, FW <---> int. if <---> 
ext. if (NAT) <---> InterNet. Let's hope it will work though.
