we have one internet link which is terminated on Internet router cisco 2921. connection as below
Internet router==>Cisco ASA 5512X===>cisco 3560 L3 switch (Vlan Created on switch & Gateway for server 10.120.8.1))====> Proxy server with single LAN card (10.120.8.5/24 & Gw 10.120.8.1)
Proxy server is Natted on ASA inside to outside with public ip & port 80,8080 & 443 is open.Site to Site VPN with HO is configured as well as Remote client VPN is configured on Cisco ASA 5512X.
Problem: if this internet link goes down then all services goes down. so we want to add one additional/Backup internet link with different ISP. Kindly suggest how to integrate with existing setup.
you can call me on below no.
