About Dl-604 Router configuration...

I have Dl-604 and Dl-704. Why only the Dl-604 has the following problem?

Dl-604 setup -
1. DHCP disabled
2. port one for computer 1 (192.168.0.100).
3. port two for computer 2 (192.168.0.101).
Computer 1 is a web server (os - w2k server, iis). Why computer 2 cannot access my website by entering e.g www.abc.com at the URL address field but it can access the website by entering http://192.168.0.100/index.htm?
Remark: If I replace the Dl-604 by Dl-704, then I can access my website both ways. I don't have any problems at all.
Whats the problem with the Dl-604?

Could the DI-604 have a DNS misconfiguration?  Or perhaps blocking DNS requests?  Maybe try factory defaulting & upgrading firmware on DI-604?
Have you configure the virtual server setting for DI-604? (tab Advanced -> option Virtual server on the left, enter the server IP there)
did check in your desktop IP dynamic configuration who is the primary DNS server with the di-604 ? is it the di-604 or....
I agree with NetExpert.  The problem is in Virtual Server.  It needs to be enabled.  Private IP should  be set to 192.168.0.100, public 80, private 80, protocol TCP, always.

On a side not, if you have ever toyed with the DMZ or enabled it the Virtual Server won't work properly.
You will need to hard reset the router for 10 seconds using the reset hole on the back.
You should probably just reset it anyways if you set the VS and it still doesn't work.
The DI-604 is an excellent router and should work fine after a reset.

I don't think it is a virtual server problem because 'but it can access the website by entering http://192.168.0.100/index.htm?' but not with 'by entering e.g www.abc.com', a virtual server problem should avoid the native IP access too, i think more it is a DNS server.

Here is my Dl-604 configurations
Firewall -
 Allow Allow to Ping WAN port WAN,* LAN,192.168.0.1 ICMP,8  
 Allow Virtual Server HTTP WAN,* LAN,192.168.0.100 IP (0),80  
 Deny Default *,* LAN,* IP (0),*  
 Allow Default LAN,* *,* IP (0),*

Virtual Server -
 Virtual Server FTP 0.0.0.0 TCP 21/21 always  
--------------------------------------------------------------------
 Virtual Server HTTP 192.168.0.100 IP (0) 80/80 always
--------------------------------------------------------------------
 Virtual Server HTTPS 0.0.0.0 TCP 443/443 always  
 Virtual Server DNS 0.0.0.0 UDP 53/53 always  
 Virtual Server SMTP 0.0.0.0 TCP 25/25 always  
 Virtual Server POP3 0.0.0.0 TCP 110/110 always  
 Virtual Server Telnet 0.0.0.0 TCP 23/23 always  
 IPSec 0.0.0.0 UDP 500/500 always  
 PPTP 0.0.0.0 TCP 1723/1723 always  

I don't see anything wrong from the above! Any suggestion?
can you test just a ping to www.abc.com with di-604 ?
Yes, I tested with a ping command and there was no problem at all (no packet lost).
If a DNS problem, then what do I need to do?
The server NIC (TCP/IP) configurations:
Use the following IP address -
IP address:          192.168.0.100
Subnet mask:      255.255.255.0
Default gateway:  192.168.0.1
Use the following DNS server addresses:
Preferred DNS server: 192.168.0.1

The Computer 2 NIC (TCP/IP) configurations:
Use the following IP address -
IP address:          192.168.0.101
Subnet mask:      255.255.255.0
Default gateway:  192.168.0.1
Use the following DNS server addresses:
Preferred DNS server: 192.168.0.1
The virtual server forwards requests from the WAN side to the LAN side.  The LAN side is wide open between machines, no forwarding.

If it's a DNS problem simply access the site using the WAN side IP (whatismyip.com).  If you get in, it's a DNS problem.  Put 4.2.2.2 in the primary DNS entry in the router.

Otherwise it's the router, since the other router works fine.

I've used that router.  If the VS isn't working right it needs to be reset.
The router always responds to ping unless you choose Discard WAN side ping under Misc. or specifically deny in VS.

Why do the computers have the router as the DNS server!?!?
Was your ping test on the name or the ip ?

'Yes, I tested with a ping command and there was no problem at all (no packet lost).
If a DNS problem, then what do I need to do?'

If ping on native IP address is ok and on www.abcname.com is not ok, then it should be DNS, if both are good, it is not a DNS problem...

the ping on name give you back the resolution of your DNS server wich is in this case your DI-604 wich support that function.

for example (sorry : in french)  :

C:\>ping www.free.fr

Envoi d'une requête 'ping' sur www.free.fr [213.228.0.42] avec 32 octets de donn

    minimum = 32ms, maximum = 47ms, moyenne = 43ms

Can you please give us back the real copy and paste of both your ping on 'name' and 'IP address' ?




Ok...I think that I need to make clear my question.
1. I can access my website by entering www.XXX.com from another network.
2. I cannot access my website by entering www.XXX.com from my local LAN.
