Won't this wlao prevent non-ipsec traffic from leaving the server ?
Oh, no, because you don't "require", only "use" if suggested by the
client, right ?
What if you want to do tunnelling and the remote end has a
dynamic IP address ? What do you fill in for "remote" below ?
spdadd 10.1.1.1 0.0.0.0/0 any -P out ipsec esp/tunnel/10.1.1.1-remote/use;
spdadd 0.0.0.0/0 10.1.1.1 any -P in ipsec esp/tunnel/remote-10.1.1.1/use;
