Site-to-site VPN Up But Won't Pass Traffic (ASA 5505's version 8.3.1 and 9.2.3)

Keegan Santos
Level 1
Level 1

Hello,

I am setting up a site to site vpn tunnel between two locations.  Both have cisco ASA 5505's running different version, i'll explain in more detail below.  so far I have been able to get the tunnel to come up but I cannot get it to pass traffic, I have been working at this for days now and have not been able to figure out why it won't pass traffic.  Needless to say the client is PO'd over the fact that their VPN isn't up and they have been having to do things by hand.  I'll put the configs below, if possible could someone help me ASAP, I really want to get this up and running so we don't lose the client.

Site A IP = 0.0.0.0
Site B IP = 1.1.1.1

Site A Version = 8.3.1
Site B Version = 9.2.3

Sorry my mistake.

Remove this if it is still there

crypto map external_map 1 set reverse-route

 

Add this to both sides

crypto map outside_map 1 set reverse-route

 

Sorry about that.

You are close....this should fix it up.

 

Site A

Remove Not needed.
no nat (outside,inside) source static NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24 destination static NETWORK_OBJ_192.168.0.0_24 NETWORK_OBJ_192.168.0.0_24

Add this, it is missing
crypto map external_map 1 set reverse-route


Site B

Remove Not needed.
no nat (outside,inside) source static NETWORK_OBJ_192.168.0.0_24 NETWORK_OBJ_192.168.0.0_24 destination static NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24

Add this, it is missing
crypto map external_map 1 set reverse-route

 

 

Hope this helps,

Mike

I tried that but still not change.  I'm curious as to where external_map one is in my configs, I didn't see it, unless i'm confused as to the way it works

Sorry my mistake.

Remove this if it is still there

crypto map external_map 1 set reverse-route

 

Add this to both sides

crypto map outside_map 1 set reverse-route

 

Sorry about that.

 

Mike

ah ok, makes sense now, still no change though unfortunately.
 

i'm not sure if this is relevant or not but i did a sh ipsec sa on site b and it is showing pkts encaps, encrypt, and digest but nothing on decaps or decrypt

i ran the same command on site a and it is the exact opposite, it has pkts decaps, decrypt, and verify, but nothing in encaps, encrypt, or digest

i compared this to a known working vpn between two other cisco asa's (running pre-8.3 so they can't help me in this case) and on the known working one there is packets in both of those areas.  

Could this indicate that site b sends and encrypts and site a recieves and decrypts, site a is not able to send and encrypt?

After look at the stats on the sh ipsec sa i figured that the tunnel is getting traffic through but the asa 8.3 isnt' sending, did a reboot on it and that fixed the issue finally, i do know the crypto helped though becuase that wasn't the case  until i did that, thank you for you help.

Glad I was able to help. One more thing that I do is remove the ikev2 if both sides don't support it or use it. I have had co-workers have it do odd things when one side has ikv2 "stuff" configured but is not using it. Based on that you could  remove

tunnel-group 0.0.0.0 ipsec-attributes
 no ikev2 remote-authentication pre-shared-key *****
 no ikev2 local-authentication pre-shared-key *****

 

Just remove the two lines with the "no", do NOT remove the tunnel-group.

 

But if it is working you could just leave it.

 

Mike
