ASA 5505 conning to VPN 3000 Concentraitor in Network extension Mode

[Sweetworks]

Ok, I've set up a group and a user on my concentraitor to allow access to my network.

I originally set the ASA in a remore site in just client mode. It connected and could use any resource at the home network, but I could not see the network on the insdie of the ASA.

I swithced to Network Extension Mode. It shows there is a tunnel. I can see the session created on the concentraitor, but no traffic (ICMP) seems to be going through.

Suggestions?

 

[North323]

have you created remote and local networks on concentrator? any rules that have been created to prevent traffic flow on either ASA or concentrator

 

[Sweetworks]

It is an existing network.

My internal network is 172.20/16
The ASA I am trying to configure is 172.26.201/24
I have a route on my DG that points
172.26/16 to the Concentraitor

I have an existing 501e Pix that is on the 172.20.1/24 network and it connects fine. I would have used the same group as teh pix but I don't know the shared password and didn't want to disrupt the existing connection it was on.

 

[North323]

has it ever worked? what are you seeing in the logs? are you getting passed phase 1?

 

[Sweetworks]

It is a new install on the Asa, but it has worked on a different Pix 501e

Here are the logs from the Live event Monitor

Note 192.168.1.120 is the IP address the ASA gets from my personal router at home. (I's plugged in at home so I can configure it from an outside connection).

 

[North323]

appears that you are passing phase two and have a tunnel. can you post a scrubbed config of the ASA?

 

[Sweetworks]

Here it is.

crypto isakmp nat-traversal 120 is missing and I do not see a gateway of last resort??

 

[Sweetworks]

I put it in and it would not allow me because I have easy VPN enabled.

 

[Sweetworks]

FYI,

I resolved it.

I recreated the config from Scratch giving it a name and IP.
I went to the VPN wizard and put it in Network Extension Mode with the proper remote groups and IP.

I created the DHCP Range.

I added the following 2 lines.

icmp permit any inside
icmp permit any outside

Starting working. I could ping through, RDP started working and so did printing.

 

[Supergrrover]

for later, you should be able to tftp the config from the pix and get the password in clear text.
