RE: Encryption question for Microsoft's ISA

Could you be a little more specific about what you mean? If you're thinking
of using ISA as a VPN server, ISA has a wrapper that simplifies
configuration of Windows 2000's RRAS (routing and remote access service).
RRAS supports PPTP and L2TP+IPSec for client remote access VPNs, and PPTP
and pure IPSec tunnel mode for site-to-site VPNs. ISA also has "dual-hop
SSL" -- ISA will inspect the certificate from incoming client SSL
connections, inspect the data (applying any necessary firewall rules), then
present its own (that is, the ISA server's) certificate to the web server.
This gives you way to inspect encrypted traffic.

Does anyone know what encryption methods Microsoft's ISA firewall supports?

Thanks,
