Static ip to multiple Routers

I'm not entirely sure I understand your question, but you should just be able to configure each router's WAN with a different static IP from within your block. So for example, if you have the IP range 50.252.60.9 through 50.252.60.13, you would assign each router a different address from within that range, and you would have each router's subnet mask, default gateway, and DNS server settings all match.

Hi jvwjgames.  The steps outlined above by train_wreck are correct.  If you will provide additional details about the end to end network setup, cable gateway>>router/ firewall>>switch>>PC, etc..the Community members may be able to provide further assistance.   If your are using a private Comcast static IP please don not included the complete IP Scope,  LAN DHCP IP scopes are ok to list.

Thank You

Ok so it goes Cable Modem>Router-1>Router-2>Router-3 and then my servers but the routers i want to have a static ip on all of them for diffrent routing and security reasons but just want the initial connection to work before i do anything else. and the cable modem does do dhcp on the lan but that is not the issue cause i can get the static ip to work if i direct connect a server to the modem.

So i REALLY don't recommend that setup; chaining 3 routers together like that is IMHO only asking for problems, and the performance hit you will likely take would be undesirable.

If you really DO want to have this setup, you will only be able to use your Comcast-provided static IP on the very first first router connected to the Comcast gateway; for the subsequent routers, you will need to configure each one's WAN with an IP address from within the subnet of the preceding one's LAN, and you would also need to keep each router's IP subnet numbering different to avoid IP conflicts, AND you would need to make sure that none of the routers are using the predefined 10.1.10.x/24 subnet that the Comcast gateway is confiured with by default, AND if you have any port forwarding rules you will need to recreate them on each router, keeping the port-to-IP mappings correct on each hop.......

I hope by now you see the drawbacks to using this setup 🙂

Train_wreck - you stated:  I don't think the Comcast business gateways will allow multiple IP addresses on one device.... I believe they enfore a "1-IP-per-device" policy.

Are you saying that I couldn't install a router that supports mulitple IPs behind the Comcast Business Gateway?

Did you eever get an answer to this one?

Hi Hege and welcome to the business forums.

What exactly are you looking to do with your statics?
