Cisco ASA 5505 site to site
Hi,
I have configured an ASA 5505 via the site to site wizard but am unsure how to diagnose or check connectivity.
Local inside IP is 192.168.3.x
Remote inside IP is 192.168.1.x
local outside ip is 86.x.x.x
remote outside ip is 79.x.x.x
I have performed same setup on remote ASA device and made sure to choose same encryption etc. All settings have been saved to flash etc.
Grateful for any help, J.

I would start by pinging first the remote outside ip is 79.x.x.x address and then the Remote inside IP is 192.168.1.x from the local end and then repeat the reverse from the other end. If all of those pings are good move on to pinging a remote PC from a local one to confirm end to end connectivity.

Thanks, this is what I got:
Result of the command: "sh crypto isakmp sa"
Active SA: 1
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 1
1 IKE Peer: 79.xxx.xxx.xxx
Type : user Role : initiator
Rekey : no State : MM_WAIT_MSG4
I am also getting lots of log messages such as:
6 Dec 21 2009 15:17:32 713219 IP = 79.xxx.xxx.xxx, Queuing KEY-ACQUIRE messages to be processed when P1 SA is complete.
5 Dec 21 2009 15:18:30 713904 IP = 79.xxx.xxx.xxx, Received an un-encrypted INVALID_COOKIE notify message, dropping
3 Dec 21 2009 15:18:54 713902 IP = 79.xxx.xxx.xxx, Removing peer from peer table failed, no match!

Ok,
so your VPN is not connecting.
Do you have a firewall behind the ASA? You might need to open udp port 500 or configure port forwarding to forward udp 500 to the 192.168.0.7

No peer match indicates that one of the ASAs is trying to build a tunnel to an IP address that isn't advertising itself as an IPSec peer at all. Make sure you don't have any typos in the external IPs of either ASA. For instance, on the config you have shown, the outside IP is 192.168.0.7. I assume that's just to have something in this example, right?
Make sure you don't have any typos in the external IPs, the crypto map set peer statements, or in the tunnel-group configs. --TX

Thanks emonda and TX. The 192.168.0.7 is the address of a netgear router connected to the internet. It does have an external IP and the ASA is set as the DMZ target so should receive all traffic (or so I thought). The asa at that end is configured correctly as firewall and has connectivity.
I am going to install the ASA in a data centre in the next few days so will have a proper external IP to set in the tunnel settings. Hopefully this will clear up the problem. I will report back and close this thread after that.

he problem has now changed and different errors are happening. This question is no longer relevant but I will accept the most relevant answer to previous problem and recreate a new question.
