Good Afternoon all,

We had a single Win2K3 DHCP server setup with a scope of - .205/24, and are using a Cisco PIX 515e as both our firewall and our default gateway.  Well, like everyone else here, we were  running out of IP addresses for it to assign.  So I thought I would setup a superscope and add another subnet.  The new member DHCP scope is - .254/24, with an exclusion range from .1 - .10.  Well, I was able to create the superscope, but when I try to assign a static address on a test system within the new .43 network, it can't see anything.  It can't even ping the gateway.  Between the client and PIX, there are no routers, just switches, and I'm thinking this is where the problem is.

Am I correct in assuming that the PIX would have to have an IP address from the new network and the DHCP relay turned on in order to forward packets between the two networks?  And that I would need an additional NIC in the PIX for this as the PIX can only handle one IP address per NIC?

Thanks in advance for your help!
