Hello,
I am currently trying to configure a Site-to-Site VPN tunnel and have seemed to stumbled into a problem. I appear to only be able to communicate in 1 direction, my 10.1.1.x clients are able to ping clients on the 192.168.135.x network; however, the 192.168.135.x clients are not able to ping clients on the 10.1.1.x network.
Topology
10.1.1.x/24 inside(ASA1)outside ===VPN===outside(ASA2)inside 192.168.135.x/24
I'm not sure which all outputs will be valuable to you to assist so let me know if I'm missing anything.

Thank you for any help you have to offer, I'm not very familiar with ASA's
Solved! Go to Solution.

Looks good from both ASA's . I hope you didn't ping from ASA1 to ASA2 after clearing sa. Do not initiate ping from ASA1 side.
#pkts encaps: 4, #pkts encrypt: 4, #pkts digest: 4
#pkts decaps: 7, #pkts decrypt: 7, #pkts verify: 7
Just to make sure, please repeat steps 1 & 2 above and ping again from pc (192.168.135.60) to pc (10.1.1.5). let it complete for exactly 10 requests.
repeat steps 4 and 5 above.
Also please check if pc (10.1.1.5). has local firewall blocking the ping.

Hello Robert,
Is it possible for you to paste complete config here?
This problem is generally due to NAT or routing issues.

Also just an FYI the second ASA is in production, we are trying to diagnose speed issues at a different facility so we created ASA 1 to bypass a suspect ASA. So I've been trying to copy the general configurations and that is why you see two peers under the crypto maps.
If you can think of anything please let me know, I greatly appreciate any help!
05-09-2015 07:43 AM
I'll try to simulate it.
Just curious, why you have this route in ASA2 ?
route outside 10.1.1.0 255.255.255.0 173.X.X.X 1
05-09-2015 10:16 AM
Thank you so much for all the help, I truly do appreciate it.
That route was something that I tried to use in a last ditch effort to try making things work before coming here and it did not make any difference. I guess I don't fully understand the the flow of logic for route creation/syntax.
05-09-2015 10:59 AM
I just simulated your config in GNS3. It works fine both ways!
Now the only way to troubleshoot it is to debug.
Can you enable debug and logging ?
If you have a very big network then use condition debugging.
Initiate traffic from subnet 192.168.135.0 to 10.1.1.0 and see debug output on ASA2.
05-09-2015 04:45 PM
Well it is a relief that it works in a way, now I just need to figure out how to find the problem. I'm not familiar with debugging at all, would you be able to assist me through the steps? How do I enable debugging and logging? Which ASA would I run this on(I imagine ASA2)?
We have a pretty large network but the connection from ASA2 to ASA1 is a much smaller picture which is why I chose that to work on. Any guidance would be great!
05-09-2015 09:21 PM
1. clear crypto ikev1 sa <peer_address> on both ASA.
2. clear crypto ipsec sa peer <peer address> on both ASA
3. initiate a ping from subnet 192.168.135.0/24 to 10.1.1.0/24.
4. show crypto isakmp sa on ASA2 and paste output here.
Also, i am attaching the config i used to simulate this. Please compare with yours and see if there is any difference. I have assumed peer address randomly.
05-10-2015 07:59 AM
What does the clear crypto ipsec sa peer <peer address> command do, I'm not familiar with SA. I will try this and post back tomorrow when I'm in the office since I need physical access to ASA1 for me to make any changes. I looked through the configuration and it seems to me like everything is the same, I'm just hoping I'm not overlooking some small detail that is throwing everything off.
05-10-2015 08:34 AM
its fine if you can do it on ASA2 only.
05-10-2015 10:12 AM
Here are the results from the commands above when I run it only on ASA2
PT-Hold-ASA5505# sh crypto isakmp sa
IKEv1 SAs:
Active SA: 1
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 1
1 IKE Peer: x.x.x.x
Type : L2L Role : responder
Rekey : no State : MM_ACTIVE
There are no IKEv2 SAs
PT-Hold-ASA5505#
That peer is the pre-existing connection that is currently working in production.
05-10-2015 10:16 AM
I spoke too soon, after I let it sit for a few minutes it now does show the two connections; here is the output:
IKEv1 SAs:
Active SA: 2
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 2
1 IKE Peer: X.X.X.X
Type : L2L Role : responder
Rekey : no State : MM_ACTIVE
2 IKE Peer: 173.X.X.X
Type : L2L Role : responder
Rekey : no State : MM_ACTIVE
PT-Hold-ASA5505#
05-10-2015 10:43 AM
Initiate a ping again and
show crypto ipsec sa
05-10-2015 01:22 PM
Here is the result of those string of commands:
PT-Hold-ASA5505# ping 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
?????
Success rate is 0 percent (0/5)

PT-Hold-ASA5505# sh crypto isakmp sa

2 IKE Peer: 173.X.X.X

PT-Hold-ASA5505# ping 10.1.1.1

One thing I did notice is if I ping the outside interface of ASA1 the ping is a successes. If I try to ping the inside interface of ASA1 or anything on that internal network it fails.
05-10-2015 11:33 PM
Can you try to ping from any other device than ASA2?
I can see that you are pinging from ASA2 itself.
if you have another device behind ASA2 in subnet 192.168.135.0/24, initiate a ping from that device to an IP in internal network behind ASA1.
