ASA Site to Site VPN , not showing up

Hi There,

I was trouble shooting a L2l vpn and was puuting captures and checking acl ,suddenly the "show crypto ikev1 sa " does not show peer MM_Active and details .

Neither in ASDM under monitor for Site to Site its showing up.

I can see that the Object group and the Site2Site config is there in the ASDM , but what is happening

Re: ASA Site to Site VPN , not showing up

Hi,
I assume the VPN tunnel was previously working or is this a new VPN tunnel?
Normally a VPN would only be established if interesting traffic (traffic matched in the crypto ACL) was transmitted. Have you attempted to send some traffic across the VPN tunnel?

Re: ASA Site to Site VPN , not showing up

it could be a number of reasons unless you share the config with us.

 

check

show crypto ikev1 sa detail

show run crypto map   | make sure you have the peer ip addres |

 

 

try to initiate the traffic from the interested ACL(source ip to remote ip address). this will tigger the VPN and then see if the crypto ikev1 sa show you anything.

Re: ASA Site to Site VPN , not showing up

Ok , sure i will do this , however i am trying to understand why this happened. I am going back in some time.
so why would this happen and just in case i still see no information after doing what you suggested ,what shall i do next.

strange thing is ,under Site to Site VPN tab i can see the config for the same ...but nothing is sh crypto Ikev1 Sa and asdm monitoring VPN.
I was seeing it till 4 hours back !!

Re: ASA Site to Site VPN , not showing up

The ISAKMP/IKEv1 and IPSec SA (Security Associations) have lifetime timers, these expire after a configured period, if no interesting traffic passes over the tunnel these SAs will not renew. Only when you attempt to send traffic over the VPN tunnel will they automatically establish a VPN tunnel, the lifetime timers start again.

If this VPN was already configured and working and you've not made any changes, potentially all you need to do is generate some traffic.

Re: ASA Site to Site VPN , not showing up

The site-to-site VPN are on demand. by mean saying this. If Alpha want to send a encrypted packet to Beta than Alpha need to initiate the connection from his/her PC. now his/her PC subnet is define on Firewall access-list (Interested traffic with reference to destination traffic). Firewall see the packet coming in and check its rule and find this rule match XYZ ACL with natting applied if there is a public address exits/or natting in place. here now ASA check its crypto config and forward the packet to the destination address as of its peer ip (which could be an other firewall/router on the internet).

 

also ikev1 and ipsec have a timer when these values. as if this was working fine and no change is made. it could be there is no initiator from your side and from remote site.

Re: ASA Site to Site VPN , not showing up

I am thankful for your answers.

i did a ping to the destination, still I don’t see MM active nor do I see any information.

acl is in place ..Asdm has config stored please 1 and 2 .

 

Just don’t know what is happening .. :(

Re: ASA Site to Site VPN , not showing up

please  share your configuration of the firewall. also would be great if you have other side config too.

 

or run these command and share the output

 

debug crypto conditon peer xxxxx     (This is the remote public ip address of the other side)

logging monitor debug

 

if on ssh connection run this command

ter monitor

Adn to disable it enter

terminal no monitor

Re: ASA Site to Site VPN , not showing up

share you vpn config and the remote site config to have a look a them. up till now we have very limited information.

Re: ASA Site to Site VPN , not showing up

Are you pinging the destination from the ASA itself? That won't necessarily work, you need to ping from a device inside the network (a switch or pc), which is a network that is defined as source in the crypto map ACL...obviously the destination network must be defined as the destination is the same ACL.

When you provide the configuration, provide information on what IP address you were pinging and what the source ip address was.
