Using carp ip as a gateway makes connection slow

[vishal.gajjar]

Hello,

We are using pfSense version 2.4.3 for HA (High Availability) mode.
Primary pfSense1’s LAN IP is 192.168.0.252
Secondary pfSense2.s LAN IP is 192.168.0.253
For HA mode we are using CARP IP 192.168.0.254 as a gateway in the network. This was working very fine since installation.

Since from 2-3 days, we are facing an issue mentioned below.
While we have set carp IP 192.168.0.254 as a gateway in any machine than connection becomes very slow. But if we use primary pfsense1’s IP 192.168.0.252 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.
