I have static NAT configured in my network with bunch of leased (Global) IP address, but suddenly my nat ip do not get internet access, where-as if i use other ip address, i can connect to the internet without any problem.
The point is that I have used the static nat for my web-server and due to this sudden problem, now it is offline.
I have following Nat on my CISCO ISR2600:
int gigabitethernet 0/1
ip addr 118.xxx.xxx.xxx 255.255.255.xxx
ip access-group 110 in
ip access-group 110 out

duplex auto
speed auto
no shutdown
exit
ip nat inside source list 1 int gigabitethernet 0/1 overload
