I am charged with servicing a wireless network where there was once a Nomadix HSG handling DHCP. The Nomadix took a dump, leaving the network unstable, DHCP was not releasing, endless nighmares with the Nomadix. They decided to not spend any time trying to upgrade S/W on the Nomadix and just use the router... entirely their call.
So, now the network looks like this:
CSU/DSU Serial Int. --> Cisco 1721 -->Switch--> VDSL to two disparate locations--->(to two segments with firetide mesh radios directional ant.) --->7 Cisco Aironet (this is an over simplification since my question is based on DHCP and the router-- this is just background info. also the APs are working correctly and have static IPs)
Right now the 1721 is doing the the DHCP but only for the pool of public addresses we have. (/25 network 128) I want to have a private network so that we can increase the DHCP pool to about 254 and still have the public IPs to give out if needed for a approx. total of 380 IPs. The 1721 has an expansion slot avail for another eth interface, and I have one at my disposal, but do I need to do that?
Can I turn on NAT and also have the public IP range on the same interface somehow using the same DHCP server thats built-in to the 1721?
I also have a follow up question about ACL changes now that the Nomadix is gone, and I can post the conf. here is someone is willing to take a look.

This may be a simple answer but I am learning and know very little about routers. Thanks.
