Hi,

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.

Hi Vinod,

I think you only need to configure ISP redundancy on the ASA device so that if the Primary ISP fails , it falls back to the Secondary One automatically.

This will work for the VPN connections as well.

Let me know if you have any queries.
