Linksys X2000 router and Fixed IP address


[link to this post]
 
Hi,
I have just bought a Cisco Linksys X2000 wireless N router for a business situation primarly as it has a second WAN port so that if the customer needs more bandwidth later I can add a second ADSL via another modem.

Because the site has a security system remotely monitored by a security company the ADSL circuit has been provided By BT with a static IP address.

My problem is that the Linksys doesnt appear to be able to be set up for PPPoA and a static IP. I have had long chat sessions with Cisco and they say the router does not have this functionality. This is something I find hard to belive when competitors such as Netgear, D-Link, Vigor etc all provide this profile. That said maybe I can still use the router in its DHCP configuration.

Am I right that if the ISP assigns a static IP to the WAN port this will never change even if the router is restarted?

I am used to configuring a device on a LAN network with static IP address rather than the network always assigning the same IP. Unless of course the principle is the same as the LAN side where you can reserve an IP address of a DHCP scope for a particular device on the network that never changes?

However usually that is associated with the MAC address of the device? If I therefore change the existing BT Voyager 220v router with the Linksys X2000 will I have to clone the old routers mac address in order to still receive the static IP?
Any help in understanding these principle would be much appreciated, otherwise I will have to return the router for a more expensive dual wan Vigor

Which ISP? And is it a single static IP address, or multiple?

No cloning of MAC addresses, all usually handled by the username/password the ISP has given you

Thanks Mr Saffron,
Its a BT business adsl and a single Static IP. Looking again at the existing Voyager 220v even this is not set up for a static IP but obtain from ISP. I assume therefore that you are correct, that the username (and password) dictates the IP address presented. I dont know much about DSLAMS and exchange equipment, or indeed if the authentication is indeed carried out at the exchange or further down the line at the ISP DNS servers?
I suppose this is a "Install it and See" situation to see if the new router does indeed receive the same IP address
Many thanks
