I run SBS2000 at the office and I want to connect to the office server from home. I have PPTP working but I would like to use L2TP/IPSec. I have two computers at home, an XPPro machine and XPHome system. I have ICS and a firewall (the one that comes w/ XPpro) configured on the XPpro machine. Can I use L2TP/IPSec on the client computer that is running NAT?
