2 Cable modems for 1 network

[thirdeye]

Yesterday I had the local cable company setup my agency with another cable modem with a line speed of 3m/768k for general use to compliment our 1.5m/1.5m that we are currently using for all 180 users and 4 VPNs. All of this is running through a PIX 515e and as far is routing is concerned, there is nothing else. I also have some 3Com layer 3 capable switches but I'm not sure what they are really capable of since I've never done much with them.

Now I know the PIX will not facilitate 2 ISP connections but I need to get something that will. I'd like to keep the PIX in place and setup a router in front of it. I'd like to be able to filter traffic depending on source for which connection it uses (ie. general users will just take the 3/768 pipe and servers and VPN traffic will take the 1.5/1.5 pipe).

You need a router capable of uplink bonding. It will also need to be able to apply filters to send different traffic to the different uplink routes. Someone else should chime in as to what can do this. I think a Cisco with OER will easily do this, but that might be overkill for your case. Not sure what lower level products they create that will have the features you need.

Ok thanks. Bump for some product suggestions

Technically that's not what I want to do. I don't want to combine them, I want one connection for users and another connection strictly for my servers/VPNs.

you're 3com switch should be able to do this for you.

more info on addressing would help.

Really? I have a SuperStack 4950 if I recall. What do you need to know for addressing. Internal scheme is 172.17.2.x with internal VPN users as 172.17.4.x connecting to another site.

Other sites connect using their own cable modems and Cisco 806 routers. I can easily change the DHCP scheme for the general users to anything I want as I'd like all that traffic to go to the 3/768 pipe and everything else to use the pipe I have now.

m0n0wall linux router with 2 wan interfaces.. use static route between them and ACL to set which traffic to which LAN interfaces.. (static nat/pat setup as well).. this can be acheived with an old PC and a couple NICs or grab something better if you want.. basically setup 2 VLAN and set a WAN connection to each. just pickup some cheap switches or use what you have.. thats up to you... keep us updated as what you accomplish.

I was thinking of using this.

If it offers enough flexibility I think I can get this to work. Anyone have an opinion on it?

Why not set up a separate router/FW for the 3m/768 connection, and point general users to it...? Otherwise, the DLink looks OK - doesn't look like there's anything in the specs indicating what you want, but you may as well get it and try

The separate router/FW is an option. I'm just looking now to make things as easy as possible.
