VPN Setup using PIX501 & VPN 3.6.3 Client

[Riteon]

This is my first trial at VPN so you must excuse my naiveity. I want to be able to access my office network (DSL static IP range 5 addresses) from home using my laptop pc and a VPN 3.6.3 Client (through ISDN/Modem dialup access). My office ADSL box has a range of 5 static IP addresses and I am running a PIX between that ADSL box and the network HUB. The PIX NAT's (I think) the internal PC's so they have access outside through one outside IP address.

Here is my current (modified slightly for security) pix setup.

Surely this is quite a simple set-up but I am worried about other people having access. What security will this 3.6.3 client have and how can I minimize risks?

My ultimate goal is to allow remote access to the intranet on our home network 192.168.1.10 and access to a mail server which is also running on 192.168.1.10 to send and receive mail and be able to drag and drop files to the hard drive on 192.168.1.10. I would also like the remote user have access to a print server on the network 192.168.1.43

I would be happy to reward the person who solves this problem for me. I have looked at different solutions but as I said before am worried about security issues.

Thanks in advance

EXTRA INFO:

The 192.168.1.10 box is windows 2000 professional PC as is the PC at home that I wish to connect to it with.

What VPN client are you referring to? Nortel?

If I am correct, you are missing some statments regarding VPN group settings. This statement will allow the authentication between your PC and PIX using a preset password. Therefore, you can change this password frequently if you are really concern people try to access your network. Additionally, you can purchase Cisco AAA server to have extra authentication but it would cost a lot of money to acquire the software.
