Okay, misunderstanding: you can not do VPN without an IP address

for the VPN peers.

If the firewall is expected to do the VPN stuff, it has

to have an IP address responding to IKE, ICMP, whatever.
But with this it is no longer a stealth (i.e. IP-addressless)
firewall.

Of course you can do VPN between two peers with a stealth firewall in
between (that is if the firewall allows), but that was not the point.
