Basic L2L VPN Lab Configuration

RadioMercy
Level 1
Level 1

I am working on getting my CCNA and am setting up a home lab.  I have 2 5506-x ASA's connected to each other via 1/1 and pc's connection via ports 1/2.  I am using the most basic configuration I could come up with.  I execute the command line configurations listed below and then use the ASDM Site-to-Site configuration wizard to attempt to bring the tunnel up and it all just fails.  The ACL is never triggered by any traffic towards the remote networks.  Here are my basic configs, the rest is done by the wizard.  Why isn't this working?

I continued researching similar issues in this community and found my answer.  I issued the following two commands and it all started working.

 

management-access inside

icmp permit any inside

 

Thank you for all of the efforts!

Hello,

 

you basically have two ASAs with empty configurations. What are you trying to build, a site to site VPN ?

Yes, I am doing the most basic configuration and then using the ASDM Site-to-Site VPN Wizard to configure the VPN but it is not working.

We do not have enough information here to be able to understand the real issue or to give good advice. We see on each ASA an outside interface that appears to be a point to point connection to a peer ASA and an inside interface that might function as the LAN for the site to site VPN. Then we get a very general statement about using ASDM. How can we see a problem in this?

 

My suggestion is to go through your process with ASDM, then pause, produce a copy of the running config for at least one of the ASAs (both would be better) and post it here. Once we can see the config that it has produced we might be better able to find the problem.

 

A second step would be after you have completed your configuration efforts in ASDM to turn on debugging for ISAKMP, generate some traffic from one ASA toward the other ASA, and post any debug output.

I am trying to configure a Site-to-Site VPN so that I can use ASDM to connect to the remote ASA.  Here is the configuration of both ASA's.  The tunnel comes up but I cannot seem to contact the remote ASA from either side.

Hello,

 

the configs look by the book. Do you have 'real' or simulated ASAs ?

Hi Georg,

 

I am using real 550x-X ASA's, they are sitting next to each other connected via gi1/1 and I have a laptop connected to gi1/2 of ASA1.  I am trying to reach the HTTP server on ASA2 so that I can use ASDM to remote configure ASA2.  I am also unable to ping the inside IP of ASA2 from the laptop connected to ASA1.

 

Thank you in advance for your assistance.
