This has got me wondering...  

 

I don't see any reason why you couldn't use a normal switch
(non-routing), and plug multiple subnets into it.  Then you could add
multiple IPs (one for each subnet) on a single ISA NIC.  As long as the
subnet mask filters out the traffic, it would be the equivalent of
VLANs.

 

That is the same concept RainConnect uses to handle up to 32 connections
on one NIC, although they use a miniport driver instead to insert the
multiple IPs.

 

But I agree (with later posts) that before a definite solution could be
defined, we would need more information about hardware, connection type,
IP ranges, etc...

 

I know where he's coming from though, I'm running three internal
Networks, one perimeter network, and one (actually multiple
w/Rainconnect) external network, all off of one ISA box.  We are using a
"true" server though, so there is lots of room for expansion.  I.e., we
have several dual NIC cards, and there are still several PCI slots left
empty.

How about 802.1q VLAN tagging?

Quad PCI NICs in two slots gives you 8 and  8 USB NICs can be done.
It'd be ugly.... and I'd hate to try and figure out what USB NIC is
which when you have an issue.....  And USB is a polled bus so your
throughput drops with more devices just even plugged into it....

 

Now, technically, you could put in a 4 slot riser card if your PCI slot
supplies enough voltage to the bus.  That right there would give him 16
NIC ports with quad cards.....   But then you'd have to lose the case
for the system......

 

Bleah, any way you cut it, change your network infrastructure......
You're going about this the hard way....

        Absolutely not. I would even doubt the MB would be able to
handle it if you could find such a device. 

         

        What you need to use is a managed layer 3 switch connected to
the LAN nic of the server. Then you use the switch to create and control
access to your various internal networks.

        dear Sir,
        i have only one server here with 2 PCI , For 2 Network Cards,
and 2 COM Ports & 4 USB Ports.
        
        this server will work as Mulithomed DHCP server for 16 Companies
in my organization. 
        
        so is there any device i can install in-order to extend the PCI
Ports from 2 to become 16 and each network card attached to it , will
conect to phisical network on the organization.
        
        can you please Provide me with thia solutions ?
