VPN Errors

I am currently getting the following errors:

Group = DefaultL2LGroup, IP = 62.73.210.70, ERROR, had problems decrypting packet, probably due to mismatched pre-shared key.  Aborting


Group = DefaultL2LGroup, IP = 62.73.210.70, Removing peer from peer table failed, no match!


Group = DefaultL2LGroup, IP = 62.73.210.70, Error: Unable to remove PeerTblEntry

The pre-shared keys are the same.

Thanks for the help in advanced.

Below is my config:

config looks ok and PSK is the same... what's on the other side; can you post the config?

also, strongly suggested to use stronger encryption/hashing than DES/MD5...

you need an entry in the dynamic-map for the site:

access-list VPNL2L extended permit ip 10.199.1.0 255.255.255.0 10.200.1.208 255.255.255.240

access-list VPNL2L extended permit ip 10.10.144.0 255.255.252.0 10.200.1.208 255.255.255.240

crypto dynamic-map myDYN-MAP 1 set transform-set mySET

crypto dynamic-map myDYN-MAP 1 match address VPNL2L

crypto dynamic-map myDYN-MAP 1 set security-association lifetime seconds 3600

I am guessing that you are using the DefaultL2LGroup because the remote site doesn't have a fixed IP address...

Patrick,

I put the commands in on my side but still I get the same errors as above.

From my ASA at my location I am able to ping the public 62.73.210.70 but not the remote ASA 10.200.1.209 or outside address of 172.25.62.226.

Thanks,

Bobby

you probably will not be able to ping the private outside address 172.25.62.226 but just its NATted public one 62.73.210.70... this is normal.

is the public 62.73.210.70 a fixed IP or it could change?

if it is fixed, then it is better to create a tunnel-group for it and not use the DefaultL2LGroup + point to it in the crypto map set peer instead of using a dynamic-map...

if it is dynamic, it has to be the one initiating traffic since this side does not know its IP address in advance...

Also, it is usually a good idea to ping a device behind the ASA, not the interface IP itself. If you want to ping the interface, you need to make sure it is allowed (some commands might be needed: management-access inside, icmp permit any inside...)

Patrick,

I also tried to ping the server behind the ASA with no luck, you are right the interfaces are not allowed.

I use defaultL2LGroup because it is easier cause of many multiple sites that change about every 3 months (Oil Rigs)

The rig is suppose to initiate the traffic via continous pings.  (rig 10.200.x.x network to me 10.199.x.x network) but the pings are failing and according to my logs here I am getting the errors listed in the main post.

Hi

Seems preshare key is not same on both side.. tunnel should not be up check sh cry is sa and sh cry ips

Thanks

Pranesh,

I did this command on each ASA in remote site and local site:

more system:running-config | inc pre-shared

Both keys were the same but I do not understand why the errors.

Thanks,

Bobby
