PIX to PIX (501's) won't work! URGENT!

Hello experts. I'm attempting to set up a site to site VPN with 2 PIX 501's.
Simply PIX 1 (192.168.0.x (inside) 82.163.165.203 (oustide)) >>> PIX 2 (192.168.100.x (inside) 62.163.122.4 (outside))

As I've never done this before I used the VPN Wizard within PDM but it gave me an error

"WARNING: This crypto map is incomplete. To remedy the situation add a peer and a valid access-list to this crypto map."

Any takers? I've posted the PIX running confs below:

Get rid of one of these crypto map sections. Keep 20 or keep 40, but remove the other one

crypto map outside_map 20 match address outside_cryptomap_20
crypto map outside_map 20 set peer 82.163.122.4
crypto map outside_map 40 match address outside_cryptomap_40
crypto map outside_map 40 set peer 82.163.122.4

Then re-apply the crypto map to the interface
crypto map outside_map interface outside

Will give that ago.... Thanks

OK, so on both Pix's I entered the command

isakmp identity address (all OK)

I then entered no to both the above statements containing 40

then I entered the reapply crypto command above. Still can't ping I'm afraid.

Can you post result of
show cry is sa <== see if phase 2 is working
QM_IDLE is good
If you don't see anything, then keep trying 4-5 times and you might see something like
MM_NOSTATE

show cry ip sa <== see if we get errors on phase 2
show access-list <== see if we are hitting the acls to even trigger the VPN

If you get zero hitcount on the access-list entries for both the match cryptomap_20 and the nat_0 access lists then we typically have a basic routing issue.

This is your client VPN, so no established tunnel with your remote peer

PIX2. I should have seen this the first time
>ip address inside 192.168.100.254 255.255.255.0
>route outside AAD 255.255.255.0 192.168.0.254 1

You have to remove that route statement!
no route outside AAD 255.255.255.0 192.168.0.254 1

Removed route statement (no route etc) Still no joy.

Les Moore

From a host inside PIX2, like from the server, setup a constant ping to a host inside of PIX 1, i.e.
C:\> ping -t 192.168.100.1

Same on site2
C:\>ping -t 192.168.0.1

Now, from the PIX console, try "show cry is sa" several times and see if you get anything like MM_KEYEXCHANGE MM_NOSTATE

Use 'show interface' and make sure you are using the correct public IP address on both ends for the peer statements.
