I need help setting up a “Business to Business (B2B)” connection from a vendor to host facility (may also be called a shared IPSEC Tunnel?). I want to add this new tunnel configuration without impacting the current setup on the PIX. Not that it matters, but the vendor has a PIX 501 and the Facility has an ASA5400. Anyhow, I have been provided the following information from the host facility:
Vendor Public IP = 216.x.x.x
Vendor Network Range = 10.129.64.0/30
Facility Public IP = 199.x.x.x
Facility Network Range = 170.x.x.x/25
SHARED IPSEC TUNNEL PARAMETERS:
Exchange mode = Main mode
Shared secret = TBD
Phase I: DH Group = 2; Encrypt = 3DES-168; Auth = SHA-1/HMAC-160; Life = 86400
Phase II: Protocol = ESP; Encrypt = 3DES-168; Auth = ESP/SHA-1/HMAC-160; Life = 28800; PFS = Off
Nat Location = Vendor Network
ORIGINAL PACKET - Source Destination = Vendor Private Net
ORIGINAL PACKET – Destination Source = Facility Private Net
