VPN is not coming UP

Hi Experts,

I have a PIX515E. I need to create a vpn to my clients office. PIX is alerady having two VPN, among two one is a dynamic VPN to a dynamic IP of netgear router.

I tried to create a new IPSEC vpn to a gateway loadbalancer.Device is PLANET MH2001. It is our client premises.

It has two gateway(public IP). Configuration in MH2001 is pretty simple. and i have completed it.

I have also completed configuration in PIX using ASDM. But the VPN is not up till now.

I have checked the logs in MH2001-->

"S2SVPN" #3701: max number of retransmissions (0) reached STATE_MAIN_I3.  Possible authentication failure: no acceptable response to our first encrypted message”

But in PIX side i didnt get log yet. I gave " sh isakmp sa" "sh ipsec sa" But it is not showing anything.... No IKE phase....

As i said MH2001 has two public IPs. and one LAN range. But i configured tunnel-group to only one public IP.

Still Nothing.. no isakmp phase for this VPN....

What should be reason???

Please see the below configuration i Have done.

Did i configure anything wrong??? or do i need to add anything more???? Please suggest...........

A.A.A.A and B.B.B.b are the two public IPs of MH2001.

access-list outside_2_cryptomap extended permit ip <insidelocal> 255.255.255.128 <outsidelocal> 255.255.255.0
access-list inside_nat0_outbound extended permit ip <insidelocal> 255.255.255.128 <outsidelocal> 255.255.255.0

VPN is not coming UP

Hi Vipin,

To begin with, I do not see command " crypto map outside_map interface outside" in your config.

Also, have a look at following links:-

For new vpn tunnel:-

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080950890.shtml

To add new vpn tunnel on PIX with existing config:-

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00807f9a89.shtml

Hope this helps,

Sian
