how can i confige one interface with many ip public address get it from ISP and how can i map each IP to server
12-21-2012 09:10 AM
i have 8 ip from ISP in the same subnnet and i have a 1941 cisco router where G0/1 it will configure as Outside and G0/0 Inside... and the inside ip address will be 192.168.1.0 / 24..... i want to make the local network go to the internet and let the people outside to see th DVR's ... where each DVR must map to a single Public IP
so i need an example to see how it is configue the router....specially the configuration of the outside port (Configure all the ip's that i have or just put the summary of them)..and the natting configue.

This document should give you a pretty good explination of how NAT works. On the right side of the document are links to related documents, this will get you started.

Thanks vmiller,
so my configure should be like that:
int g0/1
ip add 172.168.1.1 255.255.255.240 (This the range as an example have 8 IP)
ip nat outside
int g0/0
ip add 192.168.1.1 255.255.255.0
ip nat inside
ip nat inside source list 1 interface g0/1 overload ( All user should access the internet by any IP)
ip nat inside source static 192.168.1.2 172.168.1.2 (Each server mapped to exernal Ip address so it can access from the outside))
ip nat inside source static 192.168.1.3 172.168.1.3
ip nat inside source static 192.168.1.4 172.168.1.4
ip nat inside source static 192.168.1.5 172.168.1.5
ip nat inside source static 192.168.1.6 172.168.1.6
access-list 1 permit 192.168.1.0 0.0.0.255
ip route 0.0.0.0 0.0.0.0 172.168.1.254
SO is this will work....i am now want to get a right answer because i am not do that yet.

It "looks" ok,
At this point all you can do is try.
Do get your hands on the appropriate command reference and config guide for your operating system. the example in the link posted was fairly generic.
Good Luck.
