Question

Cisco ASA 5510 site to site VPN tunnel issue

Asked by: djroh

After using the ASDM wizard to setup the tunnel between two ASA 5510, I still cannot communicate between the local inside network and the remote inside network. Can anyone please take a look at my config and shed some knowledge my way. Thanks.

From the CLI, try removing (use the "no" form of the command):

crypto map outside_map 20 set pfs

from both sides and adding

crypto isakmp nat-traversal

to both sides.

Then, try a ping again and make sure the tunnel is coming up to begin with. Issue the command:

show crypto isakmp sa

And see if you see the tunel in with MM_ACTIVE state. You can also do a

show crypto ipsec sa

to see the amount of traffic being sent down the tunnel. What do you see?

by: djrohPosted on 2007-03-31 at 07:31:47ID: 18828661

Ok I have removed the crypto map_outside map 20 set pfs and selected the sho crypto isakmp sa and sho crypto ipsec sa and my resutls were:

There are no ipsec sas
There are no isakmp sas

All I still see is 0 stats. Any other suggestions.

by: djrohPosted on 2007-03-31 at 08:54:27ID: 18828839

I also added the crypto isakmp nat-traversal on both side. Still no connection. Thanks..

by: batry_boyPosted on 2007-03-31 at 14:34:26ID: 18829796

Issue the following commands:

debug crypto isakmp 200
debug crypto ipsec 200
debug crypto engine 200

Then try to ping a remote host and watch to see if you see any messages on the screen indicating that the tunnel is trying to be brought up...you should see tons of messages if it is trying.

If you see the debug messages, please post. If you don't see any messages, please post the remote site ASA config so we can compare the configs and make sure everything looks right...

Your debug output that you posted did not show that a tunnel is even trying to establish when you ping a remote host on the other side of the tunnel. What host did you try to ping?

by: batry_boyPosted on 2007-04-02 at 09:25:45ID: 18837555

Never mind...I see it.

Set up an ACL to reference in a capture command:

access-list cap_acl permit ip 10.1.1.0 255.255.255.0 host 10.1.2.6
capture vpncap access-list cap_acl interface inside

Then perform your "ping 10.1.2.6" test again from a host on the 10.1.1.0 network. Then look at your capture to see what it says and post the output:

show capture vpncap

Here is the logs and show capture vpncap below.

That looks like syslog output. I'm talking about the debug output from a console session on the ASA.

When you are pinging the remote host and are looking at the ASA and you have the debug levels for ISAKMP, IPSEC and the crypto engine set at level 200, you should see output similar to the following that shows the tunnel is trying to come up:

Do you see anything like this?

I have the debug level at 200 and the vpn capture as you have recommended. I do not see the output that you posted. I'm pinging the 10.1.2.6 and all I get is that echo request. Debug messages should pop up right on the CLI correct? I'm on limbo on this. I appreciate all your help.

by: batry_boyPosted on 2007-04-02 at 14:28:43ID: 18839763

Yes, you should see the debug output in the CLI.

I just noticed on your remote ASA config that you don't have a line that specifies the crypto ACL. You need to add a line to the remote config that looks like this:

crypto map outside_map 20 match address 110

If that doesn't fix it, please repost your current configs since I know you've made some changes since the last config posts.

crypto isakmp identity address

Let me know

by: davbouchardPosted on 2009-02-24 at 10:28:09ID: 23724579

I do not see the Crypto-map ISAKMP. Try adding following

crypto map Outside_map 20 ipsec-isakmp

This crypto map defines the IKE SA.
