TWO Pfsnese with Same WAN IP range and different Local IP range – slow network



  • Hello,

    We are using pfSense version 2.4.3

    pfSense1’s LAN IP is 192.168.1.252/24 WAN ip X.X.X.91/27 (for both pfSense WAN ip is from same range, this live ip are used as example)
    pfSense2.s LAN IP is 192.168.2.253/24 WAN ip X.X.X.81/27 (for both pfSense WAN ip is from same range, this live ip are used as example)

    ISP  –-> Switch1  ---> Pfsense 1  (Physical pfsene)
    Switch1  --uplink--> Switch2  --->  Pfsense 2 ( VM)

    Gateway for both pfsense WAN ip are same.

    We are facing slow network connection issue mentioned below.

    While we have set carp IP 192.168.2.254/24 as a gateway in any machine than connection becomes very slow. But if we use pfsense1’s IP 192.168.2.252/24 as a gateway in the same machine, then connection works very normally.

    Can someone please help us or suggest for this issue?

    Thanks in advance.
