Cross firewall VPN is indeed a reality. Vendors that build VPN's using the
new emerging IPSec protocol will interoperate when setting up VPN's. Many
of the firewall vendors have already tested for interoperability. To read
about this project go to www.rsa.com and look for information on the s/wan
initiative for IPSec interoperability.
Secure Computing Corporations two firewalls, the BorderWare Firewall Server
and Sidewinder, interoperate for VPN using the IPSec standard. Secure also
markets a Windows 95 package that does IPSec encryption (NETCourier)to
create VPN tunnels from the Windows 95 NETCourier client to the firewall,
IPSec is based on IETF RFC's 1825 - 1828 (I believe).

Yes. But the DEC encryption scheme is proprietary, not open like IPSec.
