Hi all,

I have a customer who has a Vodafone sure signal box, now to get this box working, you cant statically assign an IP to it, it uses DHCP, we dont enable DHCP on their LAN for various reasons, what I have done is logged on to the Cisco and created a DHCP pool and assigned it to a hardware (MAC) address of the sure signal box.

So command is

ip dhcp pool xyz
host 10.0.0.120 255.255.255.0
hardware address 000f.fe83.bca9 (example)
dns-server 8.8.8.8 8.8.4.4

Since doing that, with the device unplugged, from the Cisco I cannot ping that IP, once he plugs it in and does it stuff, the binding seems to be working as I can ping that IP address then, only problem the box doesnt seem to be picking up a signal although its pingable so network communication has been prooved.

Now before I done this I tried enabling a small dhcp server on their Cisco, with a pool size of 3 addresses, and it worked, it dished out the IP to the sure signal box, however, because of their network, they had issues with other workstations so I had to take dhcp server off the Cisco, that's when I then started at the static IP > MAC binding.

When it was working, we didn't have to create any firewall rules or NAT policies on their central DC hosted firewall (as they are on a private network), it just worked, but doesnt seem to be connecting to vodafone or what ever with the MAC binding method, but network connectivity is there

Any idea's what could be going wrong?

Is your MAC address IP reservation/assignment dishing out a gateway? If not the device would be pingable but would not be able to route anywhere off the internal subnet as it had no gateway.

I was thinking the same thing, the SureSignal has no route off of the network.
 
I have amended the config to

ip dhcp pool blah
host 10.0.0.120 255.255.0.0
hardware-address XXXX.XXXX.XXXX
dns-server 8.8.8.8 8.8.4.4
default-router 10.0.0.100
!


However it cannot be tested until tomorrow as the guy is not around, I have told him to reboot the box and re=test, hopefully it will, I am still able to ping the device from the Cisco but the true test I guess will be when he is on site tomorrow.
 
Unrelated to helping, but what a fail on Vodafone's part.
I understand it's designed to be a plug and forgot box for 99% of the populace but it's a simple thing. It's not like you are trying to add routes to it anything like that.
Some people don't use DHCP, so why should they be forced to?

I know, if most other devices designed to connect to a network have the option to statically assign, or pick up via DHCP, I dont see why Vodafone's box should be any different, but hey ho :p

I have heard mixed reviews about them boxes anyway, some saying they dont really do anything in terms of boosting mobile signal, some say they work okish
 
I am not sure about telnet, even if it does I dont think you can statically assign the IP to the device through its own interface anyway.

MilanoChris - I had it working the other day however that was over a proper DHCP server up on the Cisco, which I had to remove, hopefully adding this gateway will now getting it working fully without having the full DHCP server set-up and just assigning IP to a MAC Address :)
