NAT Issues

[stephen.moss88]

I am in the process of setup of a sample lab at my home.

I have my main ISP coming into my personal Linksys Wireless Router. This is being used until I have a stable environment. My family might kill me if they have no internet.

Network Topology 

• ISP (Google Fiber)
• Linksys Wireless Router
• Cisco 1841
• Cisco 3750G V2
• Test Machine

I have multi VLANS working with DHCP on a stick setup on the router. I'm guessing I have a NAT issue  because everything works but the internet. Any advice would be awesome.

Can you share full network diagram with port numbers?

Hi,

I guess you should put

ip nat inside

under each of your FastEthernet0/1.x subinterfaces instead of under  the main FastEthernet0/1?

Plus I suppose you will assign some ports to all VLANs (not only VLAN1 and 10) on your switch?

BR,

Milan

Thank you much Milan. That was the issue. And yes I will be assigning the ports to different VLANS today. This was just a trial to get it working :)

Thanks

Stephen
