Hi, I just setup an ASA 5505 and it works great, but I am having problems with a site to site VPN. I receive the information form the peer as follows:
Peer IP Address: 165.243.179.23
Preshared Key: <encrypted>
IKE security configuration: AES-256
Authentication algorithms: SHA
Diffie-Hellman group: 7
IPSec configuration: AES-256
Authentication algorithms: SHA
Diffie-Hellman group: 7
My Network: 10.1.1.0/24
Their Network: 192.168.13/24
I plugged this information into the wizard OK. The peer setup a PC using IP 192.168.13.10 for me to test ping. I see a lot of packet activity in ASDM under VPN Statistics/Global IKE/IPSec Statistics, but only for the IKE protocol, no activity for IPSec Protocol.
I have a few questions please:
1) How can I tell if we are in fact negotiating OK?
2) Is there anything in my config that would prevent me from pinging this PC device on 192.168.13.10?
3) Any other advice to help me troubleshoot this?
sh crypto ipsec sa
-->there are no ipsec sas
sh crypto isakmp sa
-->there are no isakmp sas
I attached the config file. I would really like to go back to the peer and ask questions only after ensuring everything is OK on my end.
Thank you very much for any help.

Ok, I managed to set this same ASA 5505 to a successful Site-2-Site VPN on a Sonicwall PRO 4060 peering to a 192.168.50.0/24 network and it works fine using the exact same setup and configuration as this broken peer. So I am gonna refer this ticket to the peer that is having problems.
I attached the working config to my Sonicwall PRO 4060 for those that are curious.
Thanks,

Possible typo, i.e. 192.168.13/24 instead of 192.168.13.0/24
IPSec UDP port 4500 possibly blocked
At the moment, it looks like IPSec traffic is not taking place and one reason for this may be that the UDP port 4500 or 500 is blocked.
To open the IPSec UDP ports, you need to enable NAT-T. Try the following commands on the ASA device:
