Load balancing Servers on LAN



  • Hi Team,

    I have a query with server load balancing on pfsense version 2.4.3.

    1. There are 2 servers in in the LAN network - 10.1.0.20/24 & 10.1.0.30/24
    2. A VIP has been created on pfsense for the LAN network - 10.1.0.10 /24
    3. The GW is 10.1.0.1/24.
    4. Under "Pools" created "Servers" with the IP = 10.1.0.20/24 & 10.1.0.30/24 on Port 80.
    5. Under "Virtual Servers" created with the VIP = 10.1.0.10 /24 & Protocol TCP pointing the "Servers" pool to be load balanced.
    6. An Alias has been created with name "LB-Servers" holding IP 10.1.0.20/24 & 10.1.0.30/24.
    7. A firewall Rule has been added under LAN network to allow traffic to Alias "LB-Servers. "

    Q: When I check the status of Loadbalancer,

    Pools >> Servers
    10.1.0.20/24:80 (00.0%)
    10.1.0.30/24:80 (00.0%)

    Virtual Servers >> LB-Servers
    10.1.0.10:80 10.1.0.20 Down
    10.1.0.10:80 10.1.0.30 Down

    However if I change the protocol on Virtual Servers from TCP to DNS then i see,

    Virtual Servers >> LB-Servers
    10.1.0.10:80 10.1.0.20 Active
    10.1.0.10:80 10.1.0.30 Active

    Pools >> Servers (This remains the same)
    10.1.0.20/24:80 (00.0%)
    10.1.0.30/24:80 (00.0%)

    Hope this a supported configuration. Kindly share your inputs at the earliest...

    Regards
    Viki
