Routing into a network

  • Routing from a (LAN port, gateway at, DHCP from to into a WAN gateway at, with other things connected at…

    is it possible to go from a LAN port (lets say my ip is to the "outside" at How? (can't touch the outside network config, and I need to have a / 16 on the inside)

  • LAYER 8 Netgate

    Not without specific routes for on every device that's on  Even then I would consider the configuration, umm, creative.

    In theory the longest subnet mask should win when routing decisions are made.  I wouldn't expect every client device to behave properly, however.

    Someone should renumber.  I would start with the person who made the brilliant decision to use  No possibility of a routing collision there.  Not with probably 10s of millions of networks on or  And since it's all DHCP it should be relatively easy.

  • LAYER 8 Netgate

    I guess it might also be possible to do a 1:1 NAT for the entire network so, to your LAN, it appears as something that should be sent to the default gateway.

  • even if you do, somehow, manage to get this working - it'll be a nightmare; if not now, then later.
    bite the bitter pill and go to a sane subnetting scheme

    my 2 cents
