hooking two cable modems to a 2610?

[d.anthony.hadley_2]

I have a 2610 with a NM-4E in it. Right now one ethernet is connected to a cable modem (Toshiba), which is connected to the ISP. Three other ethernet ports go to different LAN segments. I want to get more bandwidth by adding a second line from the ISP (this means a second cable modem) and plug it in to the 5th ethernet port. I would like to add Vonage IP phones to the network but route the voice traffic only out the new ISP interface. Would this configuration work? The current ISP interface gets it's IP address from the ISP along with all the DHCP parameters (using the import all command). I do have two of the LAN segments getting addresses from the router's DHCP pool. Would there be a conflict with the 5th interface getting an IP address from the ISP? Would there be any conflict configuring NAT on both ISP interfaces? It's already on the first interface. Thanks for any info.

Hi anthony,

From what you have written i can understand that you will be needing two Vlans, one for each ISP and then the configuration seems to me as straight forward.

Thanks for the response. I didn't think of two VLANs. But, it makes sense. If I'm going to have the PCs daisey chained off the vonage phones, will I have to create a VLAN trunk off the ethernet port to the switch? I will be using different IP addressing schemes for the phones and the PCs. Thanks again.
