I have guessed that I have to upgarde to v6.11

Basics are :-

(Internet) <-> Router <-> Firewall <-> Network

users internet access out using pat using firewall as g/w
users connect into lotus notes server (static mapping)

I have VPN 3.1 client

What changes do I need to make to config to allow we to vpn-dial in

Regards

David

HI.

> access-list 100 permit ip any ip.ip.ip.ip 255.255.255.0
> access-list 100 permit ip any host ip.ip.ip.ip
I think that you first need to change this, or did I miss something?

About the VPN, the best way is to upgrade to the latest pix OS, and then you have the VPN wizard in PDM that will guide and help you with the configuarion.

You should also issue the command:

show version

And check if DES and 3DES are enabled.
You can get DES activation key (if needed) for free from your dealer, but 3DES will cost you some.
