New to pfsense, basic questions



  • Hello team,

    as a long user of monowall I am in need now to have 2 WAN IPs each connected to 2 machines inside my LAN or DMZ. As monowall can't handle 2 nics on the WAN side and my ISP can give me 2 IPs only with DHCP I am looking to setup pfsense.

    From reading I understand that pfsense can handle multiple nics for WAN. Am I correct here ?

    What I liked with monowall was the option to run it without a HD, just from CD and the configuration on a floppy.

    Can I install pfsense in that way as well ? Pros and cons ?

    If some of you could give me some info on that before I start settings things up, that would defenitely be helpful to work in the right direction.
    Thank you so much.

    Yes pfSense can use multiplt WANs and can load-balance/fail-over/policy-route between them. However both your WANs will be in the same subnet which may cause some routing issues, you won't be able to fail over against them for example. Usually you could use one NIC and a virtual IP to provide multiple public IPs.

    You can do that with pfSense but it's not recommended. I would choose to run from a USB stick instead. You can't use any packages or have long term RRD graphs if you run entirely from read only media.

  • Hello Steve,

    thank you for the clarification.

    As for the 2 WAN IPs, I am not looking for a failover setup. It will be straight inbound NAT and the same subnet should be not a problem in this situation.

    Maybe I will get a bit more fancy as with monowall and will install some extra packages.  ;)
