To clarify, my suggestion was based on the assumption that Zephyr
should work with vpnc, because it uses the native tun0 interface in
the kernel, and as such, Zephyr should work, because it shouldn't care
whether it's using a VPN or not.
My understanding is that it fails with the Cisco client, because the
client goes out of its way to obfuscate the VPN's IP address from the
base operating system, so zhm sees eth0's IP address, but the zephyr
servers see packets coming from the VPN's IP address, and things fail
just like they do behind a NAT.
