I canno't spark up a VPN with a Nortel device. The peer ip is 206.210.222.130. Here is my vpn setup to connect to them dyn-map 5. The IT guy at the other end swears up and down that our device wan ip doesn't even show up in the log to even try and spark up a vpn connection.

We have a vpn setup with 4 other locations all using 506e devices. So I used the same format.

Can anyone see anything wrong with the way its setup and or know why our device hasn't even contacted their device?

Bublitz,

Well, for the most part, it looks ok. I've got three things for you:

1- add the no-config-mode & no-xauth to the end of the isakmp key statement for the 206 peer address like you have for the other one... that can't hurt.

2- your nat 0 references ACL 105. What does that look like? If ACL 105 doesn't have statements in it that are close to or identical to your ACL called "outside_cryptomap_5", then the PIX will NAT that traffic through the NAT 1 group, and it will miss the tunnel completely.

3- have you captured any logging from the PIX while attempting to bring up the tunnel? This would be helpful too in pinpointing the source of the problem...

ACL 105 has
permit ip host 172.25.2.190 host 172.18.50.4
permit ip host 172.25.2.190 host 172.20.20.23
permit ip host 172.25.2.191 host 172.18.50.4
permit ip host 172.25.2.191 host 172.20.20.23
permit ip host 172.25.2.192 host 172.18.50.4
permit ip host 172.25.2.192 host 172.20.20.23

basicly the same thing as my Crypto acl

The sonicwallim trying to connect to give me this error

IKE Iniator: Recieved notify. NO_PROPOSAL_CHOSEN

Ive checked the settings on the PIX and the sonicwall they appear to be the same I cant figure out why its not working.

What commands would I use to see debugging or logging via telnet. Can it be filtered to show only debugging for this certain vpn connection.

Bublitz,

Ok, so that log message you mentioned indicates a possible Phase 1 initiation issue... In English, it's telling you that there is no match with the peer's ISAKMP defined parameters. So, let's assume for kicks & giggles that this SonicWall you are connecting to has this ISAKMP policy defined:
Auth Preshare
encr = 3DES
hash = SHA
DH Group = 1

Your PIX has two defined ISAKMP Policies:
3des, sha, DH2
3des, md5, DH1

No match.

Why? One side can't be group 1 and the other group 2. It has to match. Now, this a mere guess as to what the other side is configured with, but it does illustrate the fact that both sides need to match. The SonicWall may not 'show' you all that the PIX will, and you may have to guess on some of the settings. I'd try settng DH1 with 3DES and SHA1 as a new policy on the PIX and see if that helps... Some of the older SOHO devices don't support DH group2.


On the PIX, you can use the | (pipe) symbol with the include command to filter down on some of the buffer logs in a telnet session.. for example, if you wanted to see anything logged with the text IKE in it, you would do:

show logg | include IKE

Hope this helps!

Ok I used the Wizard to configure this tunnel.

During the setup.

IKE Policy
Enc 3des
auth MD5
DH G 2

Transform Set
enc 3des
auth md5
(no option for DH group) My sonicwall I can configure phase 1 and 2 DH group so im not sure what its suppoed to be.

Im really not sure on the PIX which one of these is phase 1 or 2 IKE policy or transform set?

So on my sonicwall I added all these options except i put dh group 2 on both phase 1 and phase 2 negotiation.

Also id like to add during the wizard setup I have to add source or inside local ip address to outside local ip address for the tunnel. My sonicwall all I do is add outside local ips to the cisco pix im connectiong too. I do not add inside local ips for the tunnel the whole lan is useable. I hope I explained that right hehe
