I am going to install SBS2003 at a headquarters office that connects to the
Internet through a Netscreen firewall. The company has one satellite office
with 6 PCs, and I've set up a site-to-site VPN with a second Netscreen at
the satellite office. There is a third office with a single computer that
connects to the main office with Netscreen software.
All of the PCs and the existing server at HQ are in the 192.168.10.0 subnet,
and the PCs at the satellite office are using 192.168.30.0.
It seems to me that in this configuration I must use a single NIC on the SBS
box and give it an IP address in the 192.168.10.0 range. In a dual-NIC
setup, the PCs at the satellite office would only be able to see the
WAN-side NIC, and to access any server resources they'd have to log in via
PPTP -- essentially running a VPN within a VPN. That sounds like a bad idea.
Meanwhile, I'm going to set up a Windows Server 2003 standard box at the
satellite office that HQ wants access to. That, of course, will be single
NIC with an IP of 192.168.30.x.
Do I have this right or am I missing something obvious?
