3. Double click the zip file and extract it.
4. Double click and install vpnclient-win-is-4.0.2.A-k9.exe.
5. After installing you will need to reboot your machine.
6. After the machine comes back up, you will find the executable listed in Start ; All Programs; Cisco Systems VPN Client
7. Click on “VPN Client”.
8. Click on “New”

Notes for the linux users

1. You will want to grab this http://www.cts.wustl.edu/cts/vpn/vpnclient-linux.zip
2. There is an example PCF file called “cecvpn.pcf” open it and change as needed, and then save as csevpn.
3. To use, run: “vpnclient connect csevpn &”
4. If you run iptables or ipchains, you will need the following added: iptables -A INPUT -i eth0 -p udp -s 0/0 -d 128.252.21.15 --sport 500 --dport 500 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
5. This is of course the most specific you could get with the rule, modify as you see fit. Obviously, you need to modify if you are using ipchains.
6. Lastly, if there are any problems with any of this, e-mail bugs@cse.wustl.edu
