Dear all,

I bought the WNR854T, setting up is not work on static IP on some services.

I am using PPPoE at company. and the ISP have not block the port 80, 53, etc ... and after connect the internet, the ISP auto give us two DNS


I had enable the DHCP Server IP from 2 to 50. (For customers notebook)

And the Intranet all main workstation are using static IP, like 192.168.218.61-253

But I have a big big problems on some setting, list below.

1. If using the Default setting, like each computer using static IP here
IP  192.168.218.61
SubMask  255.255.255.0
Gateway  192.168.218.1
DNS1 218.102.62.71

This computer can online well,

But ... on our network, have a Linux server, it is IP 121, and it is a DNS Server for intranet test web site development...

If I change the Workstation' DNS from 218.102.62.71 to 192.168.218.121

I can not online, can not FTP, nothing can do, I had double click the Linux Server, it is working well.

I am wonder why the Netgeat WNR854T will like that.

And on the near future, we will deploy a AD Windows Server 2003, the DNS much be setting using the intranet Windows Server 2003's IP, I am wonder Netgear will work on my environment or not too.

How to solved? I have using Linksys before, also no this type of problems!!!


Thx for your time.

Are you running the most current firmware for your router?  If not, download it and install it and see if the problem resolves.  Also, after changing IP address, restart the router, flush the DNS cache and ARP cache on any machine that are having problems.

Yes , the lastest fireware on this fireware already.....

How to flush the DNS Cache and ARP Cache?

I try to reboot the XP workstation also not work

And if I change my XP workstation's DNS IP from ISP to the Linux Server IP

The Linux server's DNS also not work, but if I change back to the ISP DNS, the Linux Server's DNS work again....

Do you have the 192.168.218.0 network and the 218.102.62.0 network on the same switch?

Just only 192.168.218.x network

218.102.62.71 is our ISP's DNS Server
