PIX 501 - REMOTE VPN ISSUE

[rcravey]

Since I configured my PIX 501 to NAT to my exchange server, I am unable to conect via my remote VPN client.

When attempting to connect, it gets to the point to where it states that it is securing channel, but then it just sits there.

The log viewer states the following:

1)
received malformed message or negotiation no longer active

2) received a NOTIFY message with an invalid protocol id (0)



Any suggestions......here is my config:

HI.

> Since I configured my PIX 501 to NAT to my exchange ...
Please describe the change in more details.
What commands did you add/change? How was it before the changes?
Did you change the ip address of the pix outside interface?
Did you try to clear xlate or reboot the pix after changes?

> ip address inside 192.168.5.1 255.255.255.0
> ip local pool VPN 192.168.5.220-192.168.5.230
These are overlapping and should better be changed, to something like:
ip local pool VPN 192.168.99.1-192.168.99.10
Then change all related access-list statements.

Bye
