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 of255.255.255.0, 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
