Point to Point VPN issues
Hey...having issues trying to get a site-to-site VPN tunnel up. On my end it shows session status : UP-IDLE, IKE SA: local <ip> remote <ip> ACTIVE
But there are no active SAs. This end is a cisco 870. I've added the WAN IP of the destination site to the 'firewall' access list that is applied to the WAN interface IN to permit the host IP. I've created the crypto mapping and created the accesslist list to permit all host from the remote sites network. All encryption settings have been verified; encryption, pre-shared key, group, lifetime. On the other end a sonicwall pro2040. They do not see any session status nor do they get any errors in the log, it's as if it's not even trying to establish the tunnel. This leads me to believe the issue is on the remote sites end. I do not have access as it's another companies equipment/site. I've turned on debugging on my end for crypto ISAKMP and Ipsec, i get nothing. Is there anything anything anyone can think of on my end to check or any ideas as to what the issue may be?

Have you initiated any interesting traffic to get it to come up?An expert is a man who has made all the mistakes which can be made. -

I can't ping any address on their network and vice versa. On their end the tech said he does not see any thing in the logs regarding IKE issues or issues of the tunnel not coming up, it's as if it's not trying to establish the tunnel. I'm pretty sure the issue is not on my end, the router really does not have much configured on it, there's only one other VPN tunnel configured which is up and working, 3 access list (one for nat/firewall, one for the other VPN, one for this VPN). Are there any debug commands i can enter on my end to possibly see what the issue is? -

You mentioned you have debugging turned on but do you have term mon enabled or are you dumping to a syslog server? -

Stupid question, but you can reach the tunnel destination and vise versa? -

Definitely a good questions nerdydad! For debugs start with debug crypto isakmp.An expert is a man who has made all the mistakes which can be made.

I can ping the wan ip of the destination and vice versa, but can't reach internal network. Here's the output from sh crypto session:
