ASA 8.4 IPSec-L2L VPN 1-Way communication

RobertJLake — Tue, 12 Mar 2019 05:54:26 GMT

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

Hello Robert,Is it possible

Hello Robert,

Is it possible for you to paste complete config here?

This problem is generally due to NAT or routing issues.

Sure,Here is ASA1: Saved:ASA

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!

I'll try to simulate it.Just

ROHIT SHARMA — Sat, 09 May 2015 14:43:50 GMT

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

Thank you so much for all the

RobertJLake — Sat, 09 May 2015 17:16:55 GMT

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.

I just simulated your config

ROHIT SHARMA — Sat, 09 May 2015 17:59:25 GMT

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.

Well it is a relief that it

RobertJLake — Sat, 09 May 2015 23:45:35 GMT

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!

1. clear crypto ikev1 sa

ROHIT SHARMA — Sun, 10 May 2015 04:21:38 GMT

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.

What does the clear crypto

RobertJLake — Sun, 10 May 2015 14:59:30 GMT

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.

its fine if you can do it on

ROHIT SHARMA — Sun, 10 May 2015 15:34:56 GMT

its fine if you can do it on ASA2 only.

Here are the results from the

RobertJLake — Sun, 10 May 2015 17:12:42 GMT

Here are the results from the commands above when I run it only on ASA2

PT-Hold-ASA5505# sh crypto isakmp sa

Active SA: 1
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)

There are no IKEv2 SAs

That peer is the pre-existing connection that is currently working in production.

I spoke too soon, after I let it sit for a few minutes it now does show the two connections; here is the output:

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.

Can you try to ping from any

ROHIT SHARMA — Mon, 11 May 2015 06:33:47 GMT

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.

So I'm in the office today

RobertJLake — Mon, 11 May 2015 13:13:35 GMT

So I'm in the office today and I went ahead and attempted pinging from behind the ASA2 to a device behind ASA1 and visa versa, I have attached them as images below.

Please follow this now: 1.

ROHIT SHARMA — Mon, 11 May 2015 13:25:06 GMT

Please follow this now:

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 pc (192.168.135.60) to pc (10.1.1.5). let it complete for 5 requests.

4. show crypto isakmp sa on ASA2 and ASA1 and paste output here.

5. show crypto ipsec sa on ASA2 and ASA1 paste output here.

It'll be gud if you paste output to a txt file and attach.

Alright I have done this, the

RobertJLake — Mon, 11 May 2015 13:44:29 GMT

Alright I have done this, the pings still come out the same way, here is the output.

Looks good from both ASA's .

ROHIT SHARMA — Mon, 11 May 2015 13:53:34 GMT

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.

Okay I did as you said, no

RobertJLake — Mon, 11 May 2015 14:27:19 GMT

Okay I did as you said, no pings from ASA1 or anything behind ASA1. After clearing both ASA's of ikev1 and ipsec I went on the 10.1.1.5 PC and initiated ping 192.168.135.60 -n 10. Here are the results of the show after that.

I'm completely at a loss, I hope something makes sense to you! Also I have disabled all firewalls on the 10.1.1.5 Pc.
