Hi,
My Scenario will be like this (Please see the attached image)
Cloud (ISP)
|
Core Router
|
Firewall
My Core Router Configuration as follows:
interface FastEthernet0/0
ip address 78.*.*.* 255.255.255.*
duplex auto
speed auto
!
interface FastEthernet0/1
description "Connection to ISP"
ip address 89.*.*.* 255.255.255.*
duplex auto
speed auto
!
Now We recently purchased the following Public ip as follows :
78.*.*.* (for router)
78.*.*.* (for Host)
My Question is where and how can i configure the new router public ip inorder to access the public host ip?
HI Imran,
You could assign the new ip address as secondary ip address even though it is not a good practice to run the secondary ip address. Like
interface FastEthernet0/1
description "Connection to ISP"
ip address 89.*.*.* 255.255.255.*
ip address 78.*.*.* 255.255.255.* secondary
duplex auto
speed auto
Hope that helps.

Dear Najaf,
Thaks for your support, i tried as you suggest; still its not working
#interface FastEthernet0/1
#ip address 89.*.*.* 255.255.255.*
#ip address 78.*.*.* 255.255.255.* secondary
#no shut
Even i tried the following but not working;
Primary_Router_HO(config)#inte fa0/1.1
Primary_Router_HO(config-subif)#ip address 78.*.*.* 255.255.255.*
% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.
Primary_Router_HO(config-subif)#
Looking forward to your reply.
i have added the secondary ip to the fastethernet interface of my router
now i can ping this address from my lan
I have already added the Acl and Natting (for my local ip(10.10.3.5) to public ip)
But nothing is working.
I configured exactly same as old config; but unable to ping new public router ip as well as host ip..
u have to assing ip with /30 mask on your public interface.

I ask my provider to check the settings;
Anyhow now this is working without any changes.
Thanks for your valuable time and considerations.
