Any future plans for subinterfaces / multiple DHCP IPs on WAN?



  • In my area, Time Warner will issue up to 3 IPs (free) on my tier of service.  It would be nice to occasionally have use of the extras for things like 1:1 NAT, various network testing, etc.

    I'm not even sure how you guys would best implement it - I'm guessing through the VIP system, but it would require VIPs to support DHCP (which I know they don't in 2.0.x).

    Any plans to support this in the future?

    I guess I could work-around by plugging the cable modem into my (managed) switch and using VLANs and OPT interfaces to get the additional IPs without requiring more physical interfaces on the pfSense box… But I'd have to treat them like a multi-WAN setup, which it really isn't - just multiple IPs that I'd like to be able to use as alternate sources / rule options for "WAN."

    How are these IPs allocated? On request by DHCP? Do the requests need to come from different MAC addresses?

    Perhaps there is a single IP address and you can use an additional two on the same subnet?

    How do you envisage that would work?

    Without more details of how this "issue up to 3 IPs" happens it is difficult to answer your questions.

    Will these IPs be very dynamic? If so, what would be the use of using them as "alternate sources for 'WAN'"?
