whats not working ?

thanks.

The problem

My ip:203.33.189.0/24 can through the both ISP-A and ISP-B but couldn't get back from ISP-A and ISP-B. I'm not sure my code correct or not. Please correct my code.
possible load balancing is not working?

what is your bandwidth for both transits?

ISP-A=10Mbps
ISP-B=25Mbps
