How to configure NAT (and/or routing) to another network on LAN interface

  • Hello,

    I have the following setup

    WAN interface - standard
    LAN: 1 interface - 2 networks:
    a) - computers in LAN
    b). 217.x.x.x/27 - VoIP telephones

    a network is NATed to the internet in the most standard way
    b network does not see the internet, just extenal VoIP provider which is hooked up into the switch with this 217.x.x.x address space.

    Both a and b networks are hooked up to the PFsense LAN interface

    Pretty recently the old router died and was replaced with PFSense 2.1 appliance

    I would like to be able to access the telephones from the computers in LAN (

    Before PFSense I did it in the following way using extra linux box which is in the LAN.

    ifconfig eth0:0 217.x.x.60/27 up
    iptables -t nat -A POSTROUTING -s -d 217.x.x.32/27 -j MASQUERADE

    and adding extra route to my LAN machines:
    route add 217.x.x.32 …

    where .201 is linux box.

    Now the same I would like to achieve via PFSense.
    I made the alias via Firewall / Virtual IP and assigned it to LAN with address 217.x.x.60 and now I can ping telephones in 217.x.x.x network from PFSense box. Cannot force PFSense box to nat / route from 192 to 217 though. Could you advice what rules should I apply?

    Thank you in advance

    Best regards
