Multiple IP's on Cisco 1750

Hello,
I have a Cisco 1750 with a WIC-1ENET connected to the Internet via an ISP
provided DSL modem using PPPOE to do so.
The ISP recently provided us with multiple IP's.
The IP assigned for the PPPOE session is XXX.XXX.8.249 with a netmask of
255.255.255.0, the IP's we have available are 8 but on a different subnet,
XXX.XXX.3.16 to XXX.XXX.3.23 mask is 255.255.255.0 they state the gateway is
XXX.XXX.8.1
The Cisco Ethernet0 is connected via pppoe easy IP and correctly negotiates
a session
The FastEthernet0 has IP 192.168.0.1 assigned and using NAT option (Use WAN
interface address for dynamic source address translation) all the hosts
inside are able to surf the web. All the hosts inside have their IP fixed on
the 192.168.0.x subnet.
I also left a DHCP server running with addresses 192.168.0.100 - 150 so that
roaming machines can connect with auto settings on their network cards.
I need to create fixed routes between some of my inside machines and the
fixed IP's I have available so that they can be accessed from the internet,
Basically I need to be able to use DNS to be able to connect via the
internet to the internal machines.
one of them is a DVR server and being able to monitor it from the web is a
necessity. also to be able to connect to some of the internal hosts to run
VNC servers on them and be able for their users to connect to them is the
other requirement.
Here follows the current IOS configuration:
Is there a way to acomplish this? please help.
Thanks for your help
Jerry
