i am satish, i have a some problem about the NAT.

I wanted to add instead of edit my previous statement regarding addressing. You could use a different mask, but this will increase the broadcasts on the network. Therefore, in order to preserve and IP addresses, you could always create VLANs on your network.

Just a random thought that crossed my mind regarding this topic.

Dear Satish,

As per my understanding 124.124.211.145 is the IP of ur serial port of router and 192.168.1.1 is the internal gateway configured on eth0 of the router. If I am right abt ur given sinerio than configuration would look like below:-

*****************************************************

interface Ethernet0/0
ip address 192.168.1.1 255.255.255.0
ip nat inside
ip access-group 1 in
!
!
!
interface Serial0/0
ip address 124.124.211.145 [here u can put the subnet mask given by reliance]
ip nat outside
!
!
!
ip nat inside source list 1 interface serial0/0 overload
!
!

access-list 1 permit 192.168.1.0 0.0.0.255

*****************************************************

But still I have question in my mind that where U configured secong global IP 124.124.211.146 provided by reliance.

Swapnil /Satty,

The Static IP provided by reliance is only one that is 124.124.211.145
and 124.124.211.146 is the gateway of 124.124.211.145.

Am I right Satty.

NAT can be used at router (I don't have any idea about L3 switch) and as suggested by Zippy you can create different VLANS on your switch.

Regards.

Hey It seems that, 124.124.211.146 is the other end ip add, then no issue.
In this case my above PAT configuration will definately work.
