NAT on CARP IP ADDRESS NOT WORKING

[Verds]

Hope someone can help me to gather more information on how to check this issue.

I have 2 ISP, and each has public DNS tracking.

ISP1 - 8.8.8.8
ISP 2 - 8.8.4.4

The default route of the firewall is on ISP2, they are on load-balancing for the internal network internet connectivity.

Both ISP has /29 subnet mask and I have enabled CARP for HA.

NAT works on ISP2 using the CARP IP address from the ISP2 /29 network.

I lost internet connectivity when I'm doing NAT over the CARP IP of ISP1. Internet only works when I'm using the physical interface for NAT on ISP1.

I tried isolating ISP1 by unplugging the ISP2 to see if there is any routine issue, but the issue still persists, I cannot access the internet when I use the CARP IP of ISP1 for NAT.

Anything I need to check on my end and the service provider?

Thanks for reading my posts, any inputs will be highly appreciated.

This sounds like you're describing an issue with pfSense, but the thread is posted in the TNSR section. Are you using pfSense or TNSR?
