F5D6231 - Unable to set IP/Gateway

Hi,

My internet provider has given me the following IP and gateway addresses. When I try to enter these in the static IP configuration, I get error message from the router that IP address is invalid.

I can set these addresses directly into the Windows XP TCP/IP settings.

IP : 172.16.4.45
Subnet : 255.255.255.0
GW : 172.16.0.1

DNS : 172.16.0.1

Firmware information of the router
Firmware Version v2.00.002
Boot Version v0.00.010
Hardware 01

Thanks in advance

Mudit

Who's your ISP? I can't resolve the IP. If it's a typical ISP then the GW is usually one less than the ip.

I just got the same router as you today. I'm still trying to figure out how to set my router to use my 5 static ips.

That DNS IP doesn't even lookup, you may want to give your ISP a call back and keep them on the phone til it works.

Are you just going to be using just 1 static IP?

The internet provider is QInfiNet. Its an indian ISP using 24online software. These are the correct IP & gateway address. I think they give you one static IP address inside their private network and their own gateway.

Its like me setting a 2nd router on one port of my first router which is directly connected to my DSL modem.

DSL Modem (fixed IP address) -> Router (WAN IP from DSL modem, LAN 192 network) -> Router (WAN IP from 192 network, LAN side 172) -> My PC.

My question is that IP address 172.16.4.45, 172.16.0.1 are valid as I can set them in my TCP/IP properties in windows XP. So, why can't I set them in the belkin router ?

I've emailed belkin last week but got no response from them.

Thanks

Those are private, unroutable IP addresses. Your ISP must be using Network Address Translation.

It seems like it's bad router design, actually. Your router should allow you to enter an unroutable IP address as WAN IP, because routers can be used on private networks. Does your ISP use DHCP? If so, you can set the connection type on the router to "dynamic" and try it that way. If not, call the ISP and ask them if you can have a public IP.

I might be missing something here, too, anyone else?

Will call ISP and find if they can do DHCP but I doubt it.

I think its bad router design. I've emailed Belkin but no response. Tried calling but was on hold for so long that I had to drop it.

Does any from Belkin support team read this forum ?

Thanks

No need to call your ISP, just try connecting using "Dynamic" on the WAN side and see if that works.

I doubt anyone from Belkin posts here. After I bought my router I realized Belkin sorta sucks. I actually haven't had any troubles with mine as of yet, but from what I see so far, it's a "dumbed down" router. Why should the router care what IP address you set it to? It'll either work or it won't, but it's not the router's place to prevent you from customizing it. I can understand it displaying a "warning" message, but c'monn, don't put unneeded barriers in users' ways.

I got the following respone from Belkin.
-----------------------------------

Please note that the router will not accept a private IP address, while it is behaving as a router. This IP address will be accepted if the router is configured to behave as a switch or access point.
We suggest that you contact your Internet Service Provider and request for a valid Internet IP address.
----------------------------------

Is it true for ANY router or just this POS from Belkin ?
Unfortunately, I dont have any other router to try these IP address and gateway

If I make it as access point, will the wired and wireless PCs connected to it will get separate private IP addresses or will be able to NAT .

Thanks

Every router would perform the same in your scenario.
10.0.0.0-10.255.255.255 172.16.0.0-172.31.255.255 192.168.0.0-192.168.255.255 are all addresses used for private networks. See how far you get by assigning your computer that very same 172.16.4.45 (without the router in place).....not very far at all.

You should be able to double-NAT if you want to. There are cases where this behavior is necessary (such as this scenario).

I don't know if other routers behave like this (I have a Belkin) but it seems stupid to me.

Thats not exactly true , esp for 192.168.x.x address range.
I have tested the following setup, two cascading routers, both on 192.168.x.x network. The 2nd is in router mode and NOT access point.

DSL Modem --> (WAN) LinkSys router (LAN Network 192.168.123.x) --> (WAN IP 192.168.123.111) DLink 614+ Router connected on Port 1 of Linksys Router (LAN Network 192.168.1.x) --> Wireless PCs connected to the DLink 614+ router.

So the DLINK 614+ can route the 192.168.123.x address which is supposed to be a private network. Your "theory" is wrong.

You're telling me that you used a private address on a WAN port and from another router you were able to route to the internet?

Yes, thats exactly what I'm saying.

The DLink 614+ router's WAN IP address is 192.168.123.111 .
It is getting this IP address from the Linksys router which is connected to the DSL modem. Linksys LAN network is 192.168.123.x.

DLink 614+ router's LAN network is 192.168.1.x. I can connect
to the DLink router on its LAN side via wired or wireless connection and I do get IP address in 192.168.1.x network.

Is this not supposed to work ?????

I've the above setup running at neighbor across the street. I helped him setup his network.

Thanks

I don't see any reason that shouldn't work.
