Bill / Alvin,

Thanks to both your responses. It seems to me that the corp's firewall
really has something to do with my problem because when I dial-up to my ISP
provider (from work), instead of using the corp network, I am able to ping
my home router's public IP. However, I still can't connect thru VPN. That
may have something to do with the "pptp passthrough" you mentioned Bill.

But what I'm puzzled about is why remote desktop works thru the corp
firewall, and the pinging or VPN won't.

The reason why I don't want to use RDP is because my wife usually works on
my home pc and when I connect to it via RDP, it kicks her out of whatever
she's doing on the computer.

Thanks again,
--Francis--
