I have abit of an odd problem and a rather complex odd network however im going to make it as simple as possible just incase this is an easy fix.
I have two IP Ranges in our network
192.168.0.0 for servers (statically assigned)
10.0.0.0 for client PC's (statically assigned)
I have setup a DHCP Server and a small test range of free 10.0.0.0 addresses (its about 8 in total) on our domain controller that is on ip 10.0.0.4 I am plugging a thin client into the network and it happily gets a DHCP Address from the pool and everyone is happy.
However i have now removed that small test range from the DHCP Server and replaced it with a 172.20.10.0/24 range, but now the thin client is no longer able to get an IP address.
am i correct in thinking that because the firewall is only interested in traffic from the 10 & 192 address ranges (these are the only ones configured on its interfaces) its doing something to stop the thin client from getting an address, or blocking/dropping the traffic?
Im really not that clued up with the cisco equipment or how it works, im being promised training in the next few weeks / months but nothing has materialised yet. so im hoping until then someone here can help me out.
P.S. please do not request a copy of the firewalls config as for security im not able to provide it.
