Hello, I need to interconnect two Cisco routers (2811 and A5300) through IP, and my purpose is to use 2811 as NAT service provider to translate between Private and Public, so that office LAN can use Private IP to access the internet.
AS5300 is working as our internet gateway provider and we use static public IP addresses, for security we need to use NAT.
As shown in the attached diagram, 2811 has 2 FE, I used FE0/0 to connect to the public switch and FE0/1 is connected to private switch to provide private IP and internet accessibility.
My problem is that how to make routing between AS5300 and 2811, and also to check with me if the NAT configuration is correct.
2811 sh config
AS5300 sh config
