Firewall Wizards: RE: Netscreen-pix515 IPsec interop

Suhdeer,

A very useful site for interoperability is:
http://www.vpnc.org/InteropProfiles/

They have a list of VPN devices setup in a common manner to connect to
each other. Netscreen is listed, but PIX is not. However, the profile
for IOS may be useful.
Good Luck,
Erik

Hi,

We are using Netscreen firewall, which is configured
for site to site VPN.(Both end Netscreen firewall)
We need to replace netscreen, here.

We have cisco 515 with IOS 6.2

We are facing problem with Phase 2 nego.

Here is detail of VPN. as configured in Netscreen.

P1 proposal,(pre-g2-3des-sha)
Main mode,
Method preshare,
DH Group 2
Encrypt/Auth: 3DES/SHA
Lifetime 28800

P2 Prpoposal, (g2-esp-3des-sha)

Replay : Enable replay protection
PFS : DH Group 2
Encap : ESP
Encrypt/Auth:3DES/SHA
Lifetime 3600

Here is Pix config for above.
