I am newbee to cisco technology and hence require your help in order to configure the router for the following network scenario
so here it is
ISP WAN IP : - 1 72 .2 4 . X . X/ 3 0 ie private class IP
ISP Public Lan pool : - 1 1 7 . 2 5 4 . X. X / 29
Inside private Network - 192 .168.X.X
Now i would like to NAT my internal private network to the Public LAN Pool so that i can access inter through one of these IP and use rest for my other Public Devices.
Thanks in Advance,
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#access-list 10 permit 192.168.X.X 0.0.0.255
Router1(config)#ip nat pool Publicpool 117.254.X.X 117.254.X.X netmask 255.255.255.X
Router1(config)#ip nat inside source list 10 pool Publicpool overload
Router1(config)#interface fa0/0 - Inside Interface
Router1(config-if)#ip nat inside
Router1(config)#int fa0/1 - Outside Interface
Router1(config-if)#ip nat outside
Please have default route pointed to ISP WAN IP
ip route 0.0.0.0 0.0.0.0 172.24.X.X
if this still not working - Configure loop back with public pool ip address and try to ping any of the internet ip address with source of loopback address to see interfnet is working
Router1#interface loopback 1
Router1#ip address 117.254.X.X 255.255.255.X
Excute to below command :
ping 18.104.22.168 source loopback 1
If it doesn't work - Please share me the router configuration.
All I want to do is to access internet without changing my existing internal network configuration,
ie I want to access internet through client systems having Ip address 192.168.X.X . I am not able to so by normal configuration since the WAN IP I have been given is a Private Class IP address.
Your internal IP range looks fine.
The external IP pool range and your pulic IP address is something I need clarification on.
Question 1) Is your public IP and the pool of IP's you have got from ISP in the same range or different?
Question 2) How many public IPs do you have. One or more?
