I am running out of ips on my current network 192.1.4.x 255.255.255.0 and am having trouble determining the best way to go about it.
/ cisco 2800 series vpn router--\
wan -----cisco 2800 series ip router---switch network (win 2k3 server handling dhcp)
\ pix 506e -----------------------------/
That is an awful drawing of my setup. I have static ips setup for part of the 192.1.4.x and dhcp for the rest. I would like to move the easiest way possible to at at least 255 dhcp address and 255 static ip addresses. Optimally I would like around 510 for each so that there is significant growth room.
My first thought was to supernet a 192.168.0 address with a 255.255.252.0 subnet. I would then use 192.168.2 and 192.168.3 for dhcp and 192.168.0 and 192.168.1 for static ips. My concern with this is that my dhcp server/vpn router/pix is not letting the dhcp requests get through properly to my dhcp server so it never hands out any leases when I deactivate the 192.1.4 dhcp scope. I did connect another network connection to the dhcp server and give it a static ip on the 192.168.0 network with subnet mask of 255.255.252.0 but left the original connection to my 192.1.4 network on as well with a different subnet mask. This could be the problem or it could be impossible I do not know.
My other concern with this setup is too much broadcast traffic. Is having 1020 addresses too much on the same subnet?
Could someone please help me in determining if this is possible or if it would be a very bad idea to have all the addresses on the same subnet or suggest something else I could do.
