hi,
I am in need of an explanation of the NAT concept.
I have a single public IP address and I am trying to set up cameras over the internet. Do I open ports per camera (and how) or is the following command sufficient.
(config)#access-list 1 permit 10.10.0 0.0.0.255
(config)# ip nat inside source list 1 pool IPCAM overload
(config)# ip nat pool IPCAM 11.22.33.44 11.22.33.44 netmask 0.0.0.255
where 11.22.33.44 is my only public address
and 10.10.1.0/24 is the internal network
nat inside interface=10.10.10.1
nat outside interface=11.22.33.44
Thanks!!

Hi ,
If you are accessing your IP camera locally using port number http:10.10.10.1:8080 or http:10.10.10.1 ,use below command to NAT your IP camera for Public IP address on 8080
Post Port Nating you access it http:11.22.33.44:8080 or http:11.22.33.44
for 8080
ip nat inside source static tcp 10.10.10.1 8080 11.22.33.44 8080
for 80
ip nat inside source static tcp 10.10.10.1 8080 11.22.33.44 8080
for other port number xx is service port number .
ip nat inside source static tcp 10.10.10.1 XX 11.22.33.44 XX

Hi to add on that,
Check your cameras specifications for it may require more ports to be forwarded
