Hi gurus! :-)
I have a problem connecting VPN-tunnels. Can you see if I am missing something in the configs?
The main site Pix 501 xxxxxxxxxxxx is configured with static outside IP and should be able to handle incoming VPN Client connections as well as Dynamic LAN-2-LAN sessions from another Pix 501 on remote office.
The Remote Office Pix 501 PIX (right now configured with static IP but that IP will change) should be able to connect to the xxxxxxxxxxxx pix.
xxxxxxxxxxxx local lan: 192.168.1.0/24
PIX local lan: 192.168.10.0/24
When trying to connect from PIX (local PC pinging 192.168.1.2) I just get this debug output:

When trying to connect to xxxxxxxxxxxx with a VPN Client on internet I am getting this messages from the Ipsec Log Viewer:

What am I not seeing in this?
Thanks for your help!

NOR doesn't have an outside static IP - it gets it from DHCP via PPPOE. Are you saying that that IP will remain static though?
Try reinitializing everything on NOR - that is the one complaining about not knowing about the other side. We aren't getting to IPSec - the problem is with isakmp.
clear crypto isakmp sa
no isakmp enable outside
isakmp enable inside
Should smack it upside the head. I don't see any problems with your config, but perhaps you entered the commands out of order, and something is just askew. This will force isakmp to re read everything when it restarts via the "isakmp enable inside" command. Then try initializing the tunnel from the HBG side.

Hi
Yes, the IP is somewhat semi-static. That is: The pix gets its outside IP address from PPPoE but the ISP has assigned it to the customer, so the Nor-pix will always get the same IP from pppoe.
I will try to do the commands above, even though I have rebooted the pix several times already.
So you mean you cant see anything wrong in my config? Is it possible that the ISP is blocking some traffic maybe?
Thanks for your help!

The error you're getting in the debugs is stating that it expects to see peer information for the remote pix in its local config. In order to connect without the peer information you have to setup the remote pix as an "Easy VPN Remote Device" There are a few commands that would have to be put in the remote device to authenticate properly.
vpnclient vpngroup {groupname} password {preshared_key}
vpnclient username {xauth_username} password {xauth_password}
vpnclient server {ip_primary} [ip_secondary_n]
vpnclient mode {client-mode | network-extension-mode}
vpnclient enable
You should look at the documentation for this stuff as far as determining the mode you want to use and so forth. Also I believe the remote end has to initiate the connection, so if it times out you will have to wait for someone on the remote end to send packets your way.
Good luck
