I was forwarding a port for public viewing using the public ip. Now the internal ip is 192.168.1.150 and the public ip is 41.xx.xxx.189 I forwarded using putty shell and had the following commands ip nat inside source static tcp 192.168.1.150 80 41.xx.xxx.189 456 456 is the port to be forwarded. I realized that there was no communication because the port numbers were different. So I decided to configure it correctly and I used the command below ip nat inside source static tcp 192.168.1.150 456 41.xx.xxx.189 456 but I cant forward it. Am getting this error similar static entry (192.168.1.150 -> 41.xx.xxx.189) already exists Please help me am stuck
