Thanks in advance for your help.

Here is my setup:
--enp2s0f0: Lan with local DHCP and static IP address of 192.168.1.1 . This is working smoothly both for dynamic IPs and static IPs. For static IPs, I am mapping them in the DNS section, and that’s also working good.
--enp3s0f0: This is my first internet provider, and its connected to their modem/router that assigns IP address dynamically
--enp3s0f1: This is my second internet provide with static IP address. Clearos server is setup as a DMZ with a static IP on the modem/router, so I can route some traffic to different machines on the LAN(mainly for remote desktop access).
Everything is working fine on the LAN side, port forwarding, DNS and DHCP.
I also have multi-wan installed and setup, with 5-5 weight. Now here is the problem. Every few seconds the internet breaks connection and reconnects, and it keeps doing it non-stop. Initially I thought it was my ISP provider, but when I take clearos server out of the equation and connect directly to ISP provided modem/router, the internet works just fine. I am pulling my hair out trying to get this to work.

Thanks in advance for your help. — feeling shocked
