IPSEC tunnel won't attempt connection

I have a 5510 and a 5505 that I'm attempting to configure a simple VPN tunnel over. I have tried step by step configurations form CISCO ASA configs, as well as every source I can find. I have walked throught the config with IOS commands as well as Wizards. All my packets are dropped at the the inside or outside interface.

When I show SH ISAKMP command all I get are 0's straight down. Any ideas how I can troubleshot this

IPSEC tunnel won't attempt connection

Try the following on the 5505 (assuming your object groups are consistent with the example in the configs)

access-list outside_1_cryptomap extended permit ip 192.168.5.0 255.255.255.0 192.168.13.0 255.255.255.0

nat (inside,outside) source static NETWORK_OBJ_192.168.5.0_24  NETWORK_OBJ_192.168.5.0_24 destination static  NETWORK_OBJ_192.168.13.0_24 NETWORK_OBJ_192.168.13.0_24

Try this on the ASA 5510

access-list outside_1_cryptomap extended permit ip 192.168.13.0 255.255.255.0 192.168.5.0 255.255.255.0

nat (inside,outside) source static NETWORK_OBJ_192.168.13.0_24  NETWORK_OBJ_192.168.13.0_24 destination static  NETWORK_OBJ_192.168.5.0_24 NETWORK_OBJ_192.168.5.0_24

IPSEC tunnel won't attempt connection

Are these overlapping networks? If so then you may need to NAT one of the networks using policy NAT in order to get this to work. The document is a little dated with the nat statements but keep that in mind and see if this is what you are looking for.

IPSEC tunnel won't attempt connection

I had different networks on the inside ..13.0/24 and a..5.0/24 previously. Those didn't work either. It appears from the config guide that if my outside interfaces are on an overlapping network which they will be, then I will need to nat the outside. Do you agree?

IPSEC tunnel won't attempt connection

No the outside network is a simulation of a link on the same network. The networks that are being tunnelled from site A to site B are both 192.168.1.0/24 networks. Based on you configuration you have the same networks being protected.

Can you please label which networks you want to protect and tunnel and which ASA they current sit behind. Also i didnt see any routes configured on the ASA either.

IPSEC tunnel won't attempt connection

Sorry. In my attempt to simlify I made it more confusing.

My original config which I didn't post was as follows:

ASA 5505

Inside 192.168.5.0/24

outside 132.172.105.132/26

The route I had was 0.0.0.0 0.0.0.0 132.172.105.133

ASA 5510

Inside 192.168.13.0/24

Outside 132.172.105.133/26

The route I had was 0.0.0.0 0.0.0.0 132.172.105.132

Try the following on the 5505 (assuming your object groups are consistent with the example in the configs)

access-list outside_1_cryptomap extended permit ip 192.168.5.0 255.255.255.0 192.168.13.0 255.255.255.0

Try this on the ASA 5510

That didn't do it either. I tried a few other things after that. I suspect I have a bad device or IOS. The Organization I work for let thier Cisco support expire. It is almost back so I can get a fresh IOS. I have some other boxes I can test with. I got these boxes atfer they fired another tech who worked on these for 14 month and never got them working. I thank you for assistance.
