Hi,

I'd like set the site to site VPN between Juniper NetScreen-5GT and Juniper SRX220. I setted both devices but the VPN not working and I see error messages in the Event Log on NetScreen-5GT.

The message is:
Rejected an IKE packet on untrust from Partner1 to LocalIP with cookies cookie1 and cookie2 because Phase 1 negotiations failed. (The preshared keys might not match.).

I tried use this proposals pre-g2-3des-sha1, pre-g2-3des-md5, pre-g2-aes128-md5, pre-g2-aes128-sha1. I don't know whats the problem. I changed the preshared key several times in both devices, so I think the problem is not password problem.

Can you help me this problem?

No, different. The vpn profile name is only the label or not?

Phase 1 fails normally because a connection cannot be made. It has not gotten to Pre Shared Key (Phase 2).

Make sure the IP addresses external and internal at both ends are the same. Make sure you are using IP Subnet on both ends and that the Subnet mask is correct.

Make sure the subnets at both ends are different. They cannot be the same.

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

You can connect two different Juniper machines and connect Juniper with Cisco.

@Cook77 - concentrate on Phase 1 before Phase 2. You need to connect first.
