Newbie - Firewall and NetBIOS problems on a simple VPN con..

Archived from groups: comp.dcom.vpn (More info?)

Hi,
I'm trying to connect to my home network (peer-to-peer) using a PPTP VPN
connection through a US Robotics router. My Windows XP (where VPN server
resides) has a static IP while the other two PC on my home network get IP
the address via DHCP. No DNS. Every Workstation and Laptop has its own
firewall.
I want to ask if the VPN adaptors have to have IP addresses on the same
network with my internal LAN or my VPN server is somehow bridged to my
network adaptor in Windows XP? It also seems that NetBIOS names do not
resolv correctly as I cannot browse the network by names. I have no WINS
server.
Last question: what ports do I have to open on my local firewalls apart 1723
in order to be able to browse the network? My VPN server adaptor on the
Windows XP Pro machine doesn't show up in Sygate firewall while the other
phisical adaptors do.
