Extra security on vpn authentication

[Dennis van Vroonhoven]

Hello all,

I can connect over a vpn by connection to an ipadress and using the logon
credentials (username, password, domain). The VPN server is a W2K server
with Routing and Remote Access installed. Now I want extra security, just a
little extra so another user which knows the ipaddress and the logon
credentials cannot create a working vpn to our site. Do you have any
suggestions (links to usefull sites) to help me out with this? I was
thinking extra security using a secret key phrase or macaddress or a
certificate?

I hope you can help me out with this problem.
Thanks in advance,

Dennis

You can go for L2TP/IPSec based VPN so that you can use certificates to
control access. Refer to
