Routed /29 subnet via PPOe



  • Hi,

    I just finished my pfsense setup with Multi wan and two lan subnets and everything is working fine.

    I just found out that my ISP offers a new option to obtain a /29 routed subnet for less than 10 euros a month.

    This sounds like a great deal, so I am wondering if Pfsense would support such a setup.

    Searching the web I found some suggestions on using virtual IP's to achieve this.

    However some mention that the WAN interface should have a static address.

    My ISP delivers my ip address (and in future the routed /29) via DHCP over PPOe.

    Is such a setup supported in pfsense ?



  • Buy; Try; Keep || End ?

    I think with the PPPoE you get a semi-static on WAN ? Or does it change frequently ?



  • No, I get a static IPv4 and a static ::/48

    But obtained using DHCP and DHCP PD.



  • There is no problem doing what you mention.

    Wan will get its ipv4 probably via pppoe negotiation.
    DHCP could also work, (for ipv6 mainly).

    The /29 subnet is defined on http://x.x.x.x/firewall_virtual_ip_edit.php?id=0
    And then can be used via NAT 1:1:
    General firewall and natting rules apply, so you can adjust according to needs
    If you  need ports from the public ip to reach 1:1 natted machine , these have to be defined with the internal private ip as target.

    Works great!


  • LAYER 8 Netgate

    Or put the /29 on OPTX and don't NAT at all.



  • Thanks guys, going to enable the option and play around with it.
