I want to add a 2nd modem/router to a small SBS 2003 Server which runs ISA. Reasons are probably obvious - ISA Server makes it impossible to connect devices that the clients want to run, such as their cellphones and tablets, for pure internet access. There is either no client ISA Server s/w or the proxy settings for ISA cannot be configured on said devices.
So I'd like to introduce a new modem/router *before* the server. (Probably don't need to say this, but with ISA Server on SBS, we have a two NIC/multihomed setup).
So it would go like this...
a) Cable modem
.
.
b) (new) wireless modem/router - DMZ to server, small DHCP range for
cellphones, tablets etc.
.
.
c) DMZ IP to server via ethernet - server runs ISA Server, and from the
server the 2nd NIC connects to a modem/router
.
.
d) the modem/router from the server connects to the SBS Server client
PC's via ethernet and wireless.
So this is all setup as above, except for the introduction of b).
Can I make this happen??? I have good granular control over DHCP IP's
assigned by the server, and presumably I could run in the same subnet on
the new b) modem and use a different range of IP's? Or could I use a
different DHCP subnet on b) ???
Any advice gratefully received - including such a modem/router that can support this config.
Regards, Duncan.
