Dual wan questions - cable modems direct to pfsense



  • Hi there,

    I have been looking around the forums and it seems most people are using: http://doc.pfsense.org/index.php/MultiWanVersion1.2 to do dual wan and this article assumes that you have: ISP–->cheap router ---> PFsense

    Is this the only way to do it?

    I was hopping to simulate a dual wan router by doing this:
    ISP1 AND isp2 ---> pfsense---> LAN switch to desktops.

    that is how I have it set up right now, isp1 and isp2 go to a pile of crap dual wan netgear router but I was thinking of setting up pfsense tonight.

    Thanks for the info.

  • I've never thought using connections with private IPs and cheap routers was a very good example. When setting up dual WAN, I try to use connections with static, public IPs.
    So, to answer your question, you can connect the WAN connections directly to pfSense. Use the guide as a starting point, and just use the public ips from your wan connections. There is some mention of other setups under the 'Bridge Mode' section. It's a good document, it's just geared toward home users. I tend to think that running the ISP's crappy router in NAT router mode is the worst configuration, if you can bridge and run PPPoE/DHCP on your WAN, or have multiple IPs to allow the isp router to run with it's wan bridged to ethernet. I recognize that this is not always possible due to line configuration and/or supplied equipment.



  • Thanks dotdash,

    the setup I have is 2 cable modems (they are DHCP though, not static public ip's)

    I am trying to eliminate as much hardware as posible.

    I have built a nice "router" machine with 3 good network cards.

    so I want ISP1 and ISP2 to go directly into pfsense and then create the load balancing pools and voila.

    I found a couple documents including the 1.2 document, I will follow them and just change things as I go along.

    as long as it is possible then I shall figure it out! :)

    thanks

    did you manage to get this working ? I am planning a Dual Wan setup and would like to avoid using some consumer grade home broadband router in between my cable modem and pfsense load balancer, but the multiwan wiki says you need static ip's.  my ip isn't static, its dhcp.. so must I have some kind of NAT'ing router in front of pfsense?

    the WAN interface can handle DHCP. however the OPT interfaces cannot do this,
    so you need to have a dsl modem or other router to do the DHCP for you on the other interfaces.

    great, thanks..  I can remove the cheesy linksys router from the cable/wan side of the equation.  the DSL modem has a nat router function so that should work just fine for the opt interface
