Good Afternoon Colleagues

I hope you are doing well . For CISCO routers 871W & CISCO 2821 , May i know the maximum static nat entries like the below:

ip nat inside source static

ip nat outside source static

Best Regards

if 1:1 interface IP NAT then max is number of public IP you have
if 1:1 Port NAT then max is 65000 for one public IP or 65000Xpublic IP (if you have multi)

Thanks A Lot

Hello MHM

It is one to one static IP NAT . So there is no limitation in CISCO IOS for the number of static entries . The limitation is only the number of public IP addresses . Is that true ?
