VPN - can connect to work but work can't ping back through network.

[marshae]

I am attached to a network at home. I have verified with work that I am pinging the server there. I get disconnected on my end when work server tries to connect to pc.
My home system ISP is DSL - using winroute to support network. A network teacher at work told me that in order to use VPN I must detach my computer from network and plug directly into DSL line.
I find this hard to believe. Is this truly the case?
Any ideas on how to configure winroute to allow work server to get through firewall?
any ideas as to why this is happening.
Getting frustrated.

I have a home network with winroute pro as my firewall running DHCP server and I am able to connect to my work server just fine. I have a cable modem that connect to my winroute machine with two network cards in it. My winroute machine is then connected to a 5 port hub with the second nic and my clients are connected directly into the hub. I also have a exec. office that has a DSL with winroute lite that VPN's into our main office. It all works fine.
Are you using winroute pro or winroute lite?

You must run nat on the external network card and have the packet filtering set up correctly if you use winroute pro.
