2 ISP for failover and jitsi behind NAT

Hi. We have 2 ISP for failover and jitsi-meet server behind NAT in our private network. We configured port forvarding for bouth providers to our jitsi server and it’s work for any one of them if we change org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS= .
We can add 2 A records in DNS for 2 ip’s but jitsi wouldn’t work work for bouth public ip’s at the same time becouse of org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS option.
I try to find some workaround for this, but fail.
Maybe somebody alredy solved same task?
