Dual WAN with custom routing

    Linksys WRT54GS v1.0 dd-wrt v24r6
    I've searched the forums and played around with VLANs, etc. but I'm not really sure what the proper solution is for this problem:

    I have two ISPs, A and B. I connect to both of them DHCP, although I must use a specific hostname and clone a MAC address in order to receive an IP.

    I want to route most of my traffic through ISP B. However, I want a certain IP range (10.*) to route through ISP A.

    Additionally, I want to manage forwarded ports separately for each ISP. e.g. I might send port 22 on ISP A to, whereas for ISP B I would send port 22 to to

    Obviously both of these are ISPs so from them looking in I should look like a single computer.

    Thanks in advance,

    take a look at the Linksys RV0xx line, I do not think you can do what you want with a wrt54gs and DD-wrt. I have three WANs and I use a Linksys RV016 router. Which can do everyhting you are wanting to do and more.

    There are dual wan scripts, and "special" bulds that has reliable dual wan support. I've use them, but they do not give me as much control as a more specialized solution. pfsense, clarkconnect, & couple others may be more to your liking. Also, youl'll need a pc with multiple nic or an embedded board.

    I have 3 WAN connections that I would like to combine together. I want one connection for video games/web browsing, and then use two of the other to load balance (hopefully) my torrent traffic.

    I was looking at the PePLink Balance 30 but at 495 dollars little pricey, but the Linksys RV016 10/100 16-Port VPN Router is only 425 dollars. How is the Linksys RV016 work for you?

    Linksys makes ok hardware, but their firmware is not so great. Why not a PC running an open source load balancer.

    PepLink, HotBrick, DrayTek, etc are said to be pretty good.. as well. I like the build it yourself embedded board solution.

    What do you recommend for the routing software?

    Interesting. Did you finally pick one?

    I like pfsense & clarkconnect is PACKED with features, BUT you NEED a dedicated PC. pfsense+an embedded fanless board, is what I picked. It was a recycled soekris, a very much older model. It won't handle fios+mini-pci+vpn simultaneously as it maxes out the cpu. Using a PC for a router would be GREAT, but will be noisy and electrically costly so out of the question.

    I want to build one with sff mini case w/ 2 gigabit ports + built-in wireless mini-pci + external gigabit switch, but those sff boards + case are quite expensive and has two noisy fans.

    GET an embedded board, not necessarily a soekris, although they are quite nice compared to the others. Not cheapest, but fun to play with and useful for voip stuff too. MAKE sure you do your research BEFORE buying anything, find out about compatibility issues, find recommended hardware, as the combinations are limitless.

    it's harder to do with one single router. if you could use two routers, it'd be real easy if all you wanted to do was to have certain ip's route using the different network. just set up static routing on the main router to use the other router for specific traffic.
