Hi there, Dear Cisco Experts.

i am using cisco asa 5520 in my office which i know is old model and end of life support. but i want to ask something about load balancing.

i have configured one outside and one inside ports, outside is providing internet services to inside interface. and when my internet goes down for any reasons users are not able to use internet. so now my concern is can i deploy two ISP connection and use both on the client side, in case if one goes down then second isp start giving internet services to the client.please tel me how can i configure that settings in Cisco ASDm graphically. i will be really great full to you.

ASA  5520 only support latest 9.1 ( for Polibased routing you need 9.4 or later version)

you can do other methods with limitations : Look at the below example :
