girigv · 10-13-2009, 12:22 AM

Hi all,

i have big issue with my router.Pls help me to findout teh solution.

I hosted one website in my office server(IP:192.168.x.x) and i configure my dlink dir300 port forwarding to my public IP(202.88.xx.xx).It is working fine with 192.168.x.x but when i take 202.88.xx.xx it showing network timeout.But outside my network 202.88.xx.xx is working fine.What could be the reason for this issue .Pls help me ASAP

I have no idea what you're actually saying here. You do not forward to a public IP address, port forwarding is configured within the local network for specific ports and local network IP addresses.

Hi John,

Thanks you for your reply.

I am forwarding my local IP to a public IP that our ISP provided.From outside the network i can access it via 202.88.xxx.xxx.But from my network i can't access from 202.88.xxx.xxx. It was working when i use Di 604 dlink router

regards

Oh, now I get it. You have to have NAT Loopback on the router to allow you to access your own public IP address from inside your network. Obviously, the current router doesn't offer that option.

Exactly I need the NAT loopback support.Is CISCO RVS4000 will support NAT loopback

Why wouldn't you just access it via the internal IP on the server? Example: Your server is 192.168.1.25 and you're hosting a website on there. From out side you access it HTTP://111.222.333.444, but internal, couldn't you just access it as http://192.168.1.25? Or is there something blocking that?

Hard to believe the CISCO RVS4000 doesn't support NAT loopback, check it's configuration options.
