Phase1 SA establishment failing between Cisco Router and Netscreen

Hi,

I am trying to setup a tunnel between a Cisco router (2800) and Netscreen.

The tunnel does not come up and the debug output on cisco shows "phase 1 SA policy not acceptable!".

The configuration of all the parameters and life times are matched at both the ends.

Any thing specific to be checked / configured to make this work?

Hello,

"Phase 1 SA Policy not acceptable" basically means the Phase 1 parameters are not matching on the VPN Servers.

If possible, can you post the full debugs from the VPN Device.

Regards,

Arul

Hi,

In your crypto isakmp key configuration, can you make sure that there is no-xauth configured. For example

crypto isakmp key cisco address x.x.x.x no-xauth

If you have the "no-xauth" configured and the tunnel still does not come up, do post the router's configuration.

Regards,

Arul
