Help Needed - Cisco ASA 5510 to PIX506E VPN

Hi, I am a Active Directory / eMail / server guy who's inherited a rather complex Cisco infrastructure to manage (other guy left, they won't replace him) and I have a question about site-to-site VPN.

We have 3 offices, the main office has a Cisco ASA 5510 running version 8 and two smaller offices with PIX 506E version 6. My boss wants me to do a site-to-site VPN between the 3 locations, with HQ as the hub. The 2 remote offices have the outside interface of the PIX connected directly to the Cisco router that AT&T provided and manages, however the HQ office has a FatPipe Warp between the Cisco router and the ASA. The FatPipe is doing NAT for 3 different internet circuits and the IP address between the FatPipe and the ASA is a 172.16 address, so effectively I'm going to be double-natting (I've been researching).

I believe I am going to need the NAT transparency option enabled in the ASA, based on the docs from Cisco.

I've located all the Cisco documentation on performing a site to site VPN between PIX and ASA, but all the documentation assumes the firewall outside interface connects directly to the public side.

My question is this (and I am sure I might have others):

When I configure the VPN connection from a remote office it is asking for the public IP on the other end. I assume I need to assign one of my public IPs in the FatPipe and map it to an internal IP (172 address), or should I be mapping that public IP to the ASA's outside interface?

internet (99.x.x.x) --- fatpipe (lan 172.16.0.1) --- asa ( outside 172.16.0.250 : inside 192.168.0.250) --- inside network

thanks in advance for any help you can provide.

Jim

Yikes - big time typo, diagram should look as follows:

internet (5.6.7.8) --- fatpipe (lan 192.168.0.1) --- asa ( outside 192.168.0.100 : inside 172.16.0.1) --- inside network

I used the VPN wizard on both the PIX and ASA thru PDM and ASDM. The GUI on both sides shows there is no VPN connection and I've tried doing the SH CRYPTO ISAKMP SA returns there are no SAS.

I have to assume my problem is due to the ASA sitting behind that FatPipe and the NAT being done there, any help would be greatly appreciated.

Thanks.

why don't you just purchase the VPN add-on for the fatpipe product and terminate the L2L connection there??

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

I wasn't aware there was such an animal, networking's not "normally" my thing.

Assuming it isn't free, I probably won't be allowed to buy it.

Any idea how to terminate the L2L on the ASA with the FatPipe in the way? I've assigned a public IP and I'm NATting that to the outside interface IP configured on the ASA, but I get no traffic, nothing in the logs to indicate any kind of connection is being attempted and no SAS on the ASA.

I think I have, I'm just having issues with the ASA behind the fatpipe (combines multiple T1s), it does nat for the public IP ranges to 192.168.0.x addresses, should I be able to allocate a public IP, nat it to the outside ASA interface IP (192.168.0.100) and still get the S2S VPN to work?

According to the document the EasyVPN is only supported on the ASA 5505, I have an ASA 5510.

Brent - I appreciate the help on this, I'm not in my comfort zone here...

Ok, so I setup the VPN between the ASA 5510 and the PIX, now when I try to create interesting traffic from the ASA to the PIX by pinging an IP on the internal side of the pix from the ASA I get the following :

ASA# ping 172.16.0.129

I thick you will have to circumvent the fatpipe for the vpn. is it doing load balancing? can you post your latest config?

I've removed the fatpipe, before I did that I had nothing at all when I debugged the vpn connection, now that it's gone I'm getting the errors above.

as before, thanks in advance!

Brent,

I made the changes requested, a couple of quick questions:

1) on the asa, trying to change the crypto map outside_map 1 set pfs group1 command to group2 by using the no command and then reentering with group2 won't display the group any more, it just ends at pfs, how do I add that?

2) The pix now shows ! Incomplete for the crypto map transform-set command, I'm not sure what I did wrong.

3) should I be rebooting the ASA / PIX after these changes? using the debug crypto commands I still get the same errors about "peer table failed, no match".

Updated ASA config :
