Tunneling the same IP Subnet ( Ethernate over IP )



  • As im switching away from MikroTik routers ( one of the biggest mistakes ),
    i want to replace it with a pfsense, as its just alot faster and more user friendly.

    I've converted most configs over to pfsense and everything is working fine.

    The only issue im facing is called "Ethernate over IP",what creates tunnel where both sides have the same ip subnet.

    ( in this case 172.16.250.0/24 for the phone network for the colocation )

    is there anyway todo it with PFSense ?

    If I understand the question, you could use OpenVPN in TAP mode.

    Can i setup openvpn on a single interface?

    we have following network structure:

    location 1:
    172.16.0.0/21
    192.168.100.0/24
    172.16.250.0/24 ( phone network )
    192.168.200.0/28 ( custom ipsec )
    location 2:
    172.16.32.0/20

    location 1 and 2 need to access everything from the other side,
    and the 172.16.250.0/24 needs to be routed to the phone system in location 2 with the same subnet, same with the custom ipsec network
