I got the client to connect. Your link was not a direct answer, but helped to troubleshoot.
Event activity for telnet and http the SSG5, but no vpn client event activity.
By mistake I tried to connect Win 7 L2TP client, and event activity appeared.
I switched from wireless to NIC, and now I have vpn client event activity.
Error: initial Phase 1 packet arrived from an unrecognized peer gateway.
Unchecking "Replay Protection" in Autokey IKE advanced got the client to connect,
Pool IP assigned, no network access, but much closer.
So after hours of trying to get port 500 to work, turns out it the was the wireless adapter and Shrew Soft VPN. Dunno whats next.
I am very disappointed there is no Juniper VPN support for mobile and remote users. I cannot got back to the table and say we need to spend another $1000 for NCP VPN client software. I will rant in another thread. Thankx for the replies.
