Trouble getting VPN client to work with PIX 515e

Posted on 2006-07-14
Last Modified: 2010-03-19
I am trying to accomplish two things on my PIX 515e firewall.

I have configured it to accept VPN connections while authenticating to IAS RADIUS

I am able to connect to the PIX with the Cisco VPN 3.5 client and am able to authenticate using AD through IAS RADIUS

However, the PIX is able to assign my DNS and WINS server to my client while I am connected but it will not assign me an IP address out of the ippool I setup in my PIX. Therefore I am unable to actually do anything once I am connected to the PIX from the outside. I have the proper DNS server ( but my IP address stays the same (

I am also trying to route port 443 to our mail server( for OWA and have been unable to successfully accomplish that as well.

Here is my config file

Have you looked the log to see if there are any errors?  Once you are connected, from the cisco client, click on Status->Statistics.  What do you see under Address information for the client and server?

Here's some issues that will affect what you're trying to do:
This acl looks like your're on the right track to bypass nat for inside - > VPN clients
>access-list 101 permit ip
>nat (inside) 0 access-list 101

BUT, that acl 101 does nothing because your internal LAN is 10.1.19.x not 10.1.9.x
>ip address inside

AND, your ip pool is not that I would expect looking at the no-nat acl above
>ip local pool ippool

This route entry will hinder your ability to use any 10.x.x.x IP address as your VPN client pool
>route inside 1

no ip local pool ippool
ip local pool NEWPOOL
vpngroup vpn3000 address-pool NEWPOOL

no access-list 101
access-list 101 permit ip
nat (inside) 0 access-list 101

>Cisco VPN 3.5 client
HIGHLY suggest upgrading to latest 4.8 VPN client to work with XP/SP2 and all the latest MS updates

Just add new acl entries for it:
access-list outside_in permit tcp any host 206.***.***.*** eq http
access-list outside_in permit tcp any host 206.***.***.*** eq https

and re-apply the acl to the interface
 access-group outside_in in interface outside
