How to configure 1921 ISR to redirect request to external IP address to an internal IP address?

Hello,

I'm fairly new to Cisco IOS and but I have setup an office network using a Cisco 1921 ISR.

Let say our public IP address is: 123.123.123.123

Our internal network IP is 192.168.255.0/24. I have an internal HTTP server running on 192.168.255.10. The Cisco 1921 is configured to allow port forwarding from 80 to 192.168.255.10 as well.

I can access my HTTP server from external networks using 123.123.123.123. However, when I'm on my internal network, I cannot access my HTTP server using 123.123.123.123, but I can access it using 192.168.255.10.

Is there a way to configure the Cisco 1921 to redirect any traffic going to 123.123.123.123 from the internal network to 192.168.255.10?

 

Thanks,

Colin Zhu
