Please help! What are the errors mean?

Juniper netscreen 500

IPSec can be a trick and its even worse when going between vendors. I would set it up between two mikrotiks first and get it working. Then try changing it to connect to the juniper. I know this is hardly help. I try to avoide IPSec unless needed.

I have same problem between two mikrotik devices after upgrade to 6.0rc12

Give it a try with 5.24. I don’t have any IPSec tunnels with 6 yet so I can only assume that it should work fine. My first thought is that you have probably isolated the issue a bit more. If you need me to look over your config screen shot the pages and email them to joshaven(at)dmcibb.net. I use skitch which is a free screen shot tool that allows me to easily redact private info.
