Two ADSL - PfSense - Single Gateway - Multiple IP block [ SOLVED ]



  • Hi,

    I have currently working system as follows:

    ADSL Modem1 –-->WAN1---|                                  |                                |---------------> DHCPClient1 ( 192.168.1.X )
                                              |  pfSense                      |                                |
                                              | Gateway: 192.168.1.1  |  –-----> LAN -------- |----------------> (192.168.1.Y ) (From DHCP Server Static Mappings)
                                              | Subnet: 255.255.0.0    |                                |–---------------> Another DHCP Client (192.168.1.Z)
                                              |                                    |                                |
    ADSL Modem2 –-->WAN2---|                                    |                                |-----------------> Another Static Mapping 192.168.1.T

    I want to achieve follows:

    ADSL Modem1 –-->WAN1---|                                  |                                |---------------> DHCPClient1 ( 192.168.1.X )
                                              |  pfSense                      |                                |
                                              | Gateway: 192.168.1.1  |  –-----> LAN -------- |----------------> (192.168.2.Y ) (From DHCP Server Static Mappings)
                                              | Subnet: 255.255.0.0    |                                |–---------------> Another DHCP Client (192.168.1.Z)
                                              |                                    |                                |
    ADSL Modem2 –-->WAN2---|                                    |                                |-----------------> Another Static Mapping 192.168.2.T

    To make it more clear, I want to be able to add static mappings, in 192.168.2.BlaBla IP block. When I enable this by using Static Mapping under DHCP Server setting menu, it works. My client gets 192.168.2.106 for example.

    But my client can not access internet. When I set my client static mapping to 192.168.1.106, it can access to internet.

    What could be wrong ?



  • The issue is solved. In Static mapping, I had to select IP blocks different than my ADSL modems. As you see above, my Modems (WAN Interfaces) sit on 192.168.2.x and 192.168.3.x

    So, when I set Static mappings for my client devices as 192.168.2.x and 3.x; those devices fail to access internet.

    I choose 192.168.0.X or 192.168.4.X, and devices succesfully connected to internet.

    Thanks for helps.
