Hello,

I am using the 2WIRE 2701HG-B. It recognizes all devices on the network except a networked DVR.  I am unable to forward ports to it without it being recognized.  I can internally view the DVR. The DVR and Gateway are otherwise working properly.  

I linked to a previous question where this was suggested:
MikeKane:
I'm just throwing this out there.....    Could you assign the IP of the DVR to another Host in the network temporarily.  Then setup the Rules as needed and save them to the router.     After which, reassign the IP back to the DVR.  

Is this currently the best solution and if so, can I get some more direction on how to "assign the IP of the DVR to another Host."

Thanks,
JE

What do you mean by recognize? Have you verified the ip configuration of the DVR. Are other computers on your network able to ping your dvr. I am assuming the 2wire can't.

I mean I don't see it in my "home network" and when I try to port forward, the dvr is not in the drop-down menu for the 2WIRE Gateway, like the other devices are.

Thanks,
JE

Can you ping the dvr's ip address from other computers? Can't you statically add it's ip address in the port forewarding page?

"Can't you statically add it's ip address in the port "  - I can't find a way on how to do this with this Gateways interface.

"Can you ping the dvr's ip address from other computers? "
Perhaps you could help me with this task?

For windows go to start, run, type in cmd and hit enter. A black window will pop up. Then type in ping and the IP address of the dvr . So for example :
Ping 192.168.1.2 then enter.  If you get replies you have connectivity to the dvr

Doesn't the MAC address of the DVR show up in the 2Wire's "local network device list"?  You'd locate its mac address on the list, see the corresponding IP address, and then go to the local network address allocation page on the 2Wire, and assign the same IP address, so it'll be fixed and unchanging (static).  Once you've done so, you'd just forward the necessary ports to that IP address.

Soulja:
Yeah, I guess I already knew how to do that.
I am able to sucessfully ping the dvr from other computers on the network.  I assumed this was the case as I am able to view the DVR within the network.

akahan:
No, nothing about the DVR shows up.  I was able to add the mac address manually with the 2WIRE Gateway but this also did not result in the DVR being shown in the "local network device" list.

Please advise,
Thanks,
JE

Is the DVR connected to the network?  If so, how do you know it is?  What does "I can internally view the DVR" mean?  How do you view it?  What do you view?

Yes.

I can successfully ping the DVR from any machine on the network. Also the DVR is hard connected to the 2WIRE

>What does "I can internally view the DVR" mean?  How do you view it?  What do you view?
I can view the DVR from any machine on the network. (Trying to port forward for external viewing). The DVR is for a CCTV system. If I enter the DVR's address into a browser I can the view the CCTV Feed as long as the machine is on the same network.

Thanks again,

"I can successfully ping the DVR from any machine on the network. Also the DVR is hard connected to the 2WIRE"

OK, we're going step by step here...  if you can ping the DVR, you must know its IP address on your LAN.  How do you know what the DVR's IP address is?  Is it set statically in the DVR's setup?

When you view the dvr over your lan throught the browser are you using any special port or just http? For example when you go to your browser to you put in:

http://dvripaddress:port#
or

http://dvripaddress

What model 2wire do you have, or can you post the manual. It should have a port forwarding option where you enter the ip address of the dvr and the ports you want to forward.

Hello,

I use http://dvripaddress:port#.

The model is 2WIRE 2701HG-B. It has a port forwarding option, but it only allows me to use recognized devices.  As far as I can tell there isn't an option to enter the IP address manually.

I just switched to the this 2WIRE device. I access the Gateway by going to http://homeportal  , It's interface has far less options than the previous 2WIRE.

Cheers,
JE

One the summary page of the 2wire does it show any unknown devices? Have you tried pinging the dvr from the 2Wire device?

Hello,
It does not show any unknown devices. Aside from the PING operation listed above, how does one PING the DVR from the 2WIRE device?

Thank you kindly,
JE

The 2Wire is SUPPOSED to list statically assigned devices by IP address in the list of "local devices" on the Network Summary page.  It appears that your 2Wire device is not detecting the DVR, for whatever reason.

I wonder if it would make sense to configure the DVR so that it requests an IP address from the 2Wire using DHCP (which should certainly cause the DVR to show up in the list of local devices on the 2Wire.  Then, once it has done so, you would go to the local network address allocation page, and set up a DHCP mapping for the DVR, so that it always gets the same IP address through DHCP, so that your port forwarding will work consistently.

akahan:

I was previously using dyndns.org to update my IP address as my internet service does not provide a static one.  Would the DHCP solution be affected by this information?

Soulja:
The interface for changing the setting with this 2WIRE is horrible.  I can not find that which you suggest.

Thanks again,

The dhcp option will not be affect by dyndns. Dyndns only concerns your WAN ip address that changes dynamically. No LAN addresses is affected by it. I would try akahan solution.

You are confused.

The two have absolutely nothing to do with each other.

Your connection to the internet is your WAN IP address.  It is the IP address at which other people out on the internet would find your router.  It is the address of the internet-facing side of your router, and is assigned by your ISP.

Your WAN IP address changes from time to time, as it's non-static.  When you are not using it, your ISP might assign it to someone else.   What Dyndns does is allow you to give a name to your location, which stays the same all the time (like justearth.kicks-ass.com or whatever) and it keeps track of your changing numerical IP address, and makes sure that the name always points to the current numerical address.    So that, even though your numerical IP address changes from time to time, justearth.kicks-ass.com will always point to your router.  Because every time your router is assigned a new numerical WAN IP address it *tells* the DYNDNS server "I just got assigned a new IP address, please reassign my name to that address."

On the local (LAN) side of the router, each of your machines has an IP address on your local network.  These addresses have NO RELATION at all to the the address on the WAN side.  You can think of it as if your network was an apartment building:  the WAN address is like the street address (59 Oriole Road, or whatever), and the LAN addresses are apartment numbers (101, 102, 103, etc.)  

As the owner of the apartment building, YOU have control over how you number the apartments.  You have no control over the address of your building, however, and the two are unrelated.   The apartment next door might have apartment numbers identical to yours, but what disambiguates your apartments from the apartments next door is the different street address.

You can choose to allow your tenants to tell you what number they want put on their individual apartments (static addressing), or you (the router) could assign which number goes to which apartment from time to time (dynamic addressing).  If you choose the latter approach, you can give the apartments different numbers when you wake up each day (a bit chaotic, but that's what DHCP normally does), or you could keep a list of which number should be assigned to which apartment, so that the apartments get the same numbers consistently.  (This is also DHCP -- the numbers are being provided by the router -- but the router "remembers" which apartment should get which number, even when the router has been turned off or rebooted.  That's what "address allocation" is all about.)

Either way, your street address is out of your control.

When you get "mail" addressed to your (router's) street address from the outside world, your router has to decide which apartment (computer) to send it to.  That's what port forwarding is all about.  The router knows that "any mail addressed to port X should be delivered to apartment Y."   In order for this to work, apartment Y always has to have the same number.  It can always have the same number because (a) it's assigned statically (by the tenant/computer), or (b) because the router knows to always assign the same number to that apartment (because it's set in the router's address allocation table).

If you do neither (a) nor (b), then the apartment has a number that does not permanently correspond to the particular tenant (computer), so port forwarding will be unreliable, to say the least.


I hope that explanation doesn't just make things worse.

Hello,
In the DVR settings I changed the network type to DHCP. I then changed the address to "private fixed" in the gateway. I think will prevent it from changing.  

It appears to work!

Thanks,
JE
