Re: NAT Loopback : Low bandwidth

Hi there,
I have a WNDR4500 first generation as my lan router, behind the internet gateway.
There is a server on the LAN and some clients (smartphones, computers) access it from both LAN and WAN using the internet domain name.
I recently found out that the bandwidth is very low while client devices are on the LAN. When I change the server details on the devices with a LAN IP address, full network speed is available. Therefore, I suspect that the NAT loopack function on the WNDR4500 is not functioning properly and reduces the available bandwidth to less than 1 MB/S. The internet connection is down: 40mbits / Up: 8mbits.
I checked QOS parameters and all seems fine, e.g. no change when inputing a large number on the internet bandwidth.
Anyone experienced this issue?
Thanking you in anticipation.
Solved! Go to Solution.

Based from engineering, the only way to get this working is through the use of IP address.
There will be no firmware updates to correct this since the device is already EOL.
I apologize for any inconvenience this may have caused you.

Re: NAT Loopback : Low bandwidth
Welcome to the community, @birdie377
What is the exact changed you made on the router to get full network speed?
What's the firmware version loaded on your router?

Re: NAT Loopback : Low bandwidth
I would like to confirm that the slow down happens when accessing the server from the LAN side, correct?
If someone from outside your network tried accessing the server, will you experience the same?
And when you say bandwidth very low, is this the Internet access? Or it is something else?
Is the slow down happening on the wireless or it doesn't matter?
Did you check all your DNS settings on the server side?
By the way, what kind of server do you have?
