Contivity to PIX VPN with digital certificates

Level 1

Hi.

I am trying to raise a VPN between a Network Contivity appliance and Cisco PIX Firewall with digital certificates and not with preshared key, but the VPN does not rise. We have followed the steps for the configuration of VPN with digital certificates generated by an CA described in the manuals of Cisco PIX.

I attach the log's generated by both machines.

If there is a setting for pre-shared key authentication using ID type, if the ID type is set to ID_FQDN the contivity will give an error in invalid ID, the ID type on the Pix needs to be set to IPV4. Also PIX has to be configured for IKE identity negotiation instead of the hostname which is done by default. Hope this helps.
