Cisco Pix to ASA - Site to Site VPN not coming up

Posted on 2009-07-09
Last Modified: 2012-05-07
I am attmepting to setup a second site to site VPN tunnel on a Cisco Pix 501.  I am having trouble with it.  This is first time where the destination fiewall (cisco ASA) subnet is not a private subnet and I believe this is throwing me off.

The ASA's firewall IP is, whereas its subnet that I need to communicate with is  The local subnet on the Pix is 192.168.73.x.

I turned on the logging and this is the only thing I am seeing.

IPSEC(sa_initiate): ACL = deny; no sa created

The pre-existing vpn tunnel is working just fine.

Curent config of the Pix is below.  Any ideas?

What version PIX code are you running?  

Are you licensed for more than 1 peer?  

Make sure the nonat on the far side of VPN matches exactly the nonat on this unit.

The Pix is running 6.3.5.  
If you mean IKE peers, that is showing we are licensed for 10.
The ASA on the other side is using something like this, but I dont know how to implement this on the Pix since I am going to have multiple tunnels.

nat (inside) 0 access-list 101

Can this command be entered multiple times for different access lists?

When I use a nat 0 for multiple tunnels, I've always just added the source and dest to the same nat0 acl.   I don't think you can have multiple Nat 0 on the same interface since it would probably mess with how the ACLs are processed, which ACL would be applied 1st, etc...  

BTW, having a non-private range as the destination of a VPN tunnel makes no difference.   Your firewall doesn't care, it will match the destination to the ACL and nonat it, or catch it in the crypto match....  

Everything looks ok to me.  Any chance we can see the code or some logs on the far end of this tunnel

We were able to get this working.  I had the config on the ASA rebuilt and the tunnel then came up.  Thanks for the help!
