Hello Experts,

Please have a look at my diagram I've mentioned all required information


- We are using Microsoft TMG Firewall as a web proxy for our internal clients. Its has 2 NIC External connected to ASA and Internal connected to Switch.

- We are going to add a new ISP, now I want that proxy should route all the internet traffic to New R2_ISP2 as primary, if ISP2 fails he should automatically route to R1

- I want to keep R1 now for VPN Traffic and Inbound Services a nd as backup if  R1_ISP2 fails for outbound internet traffic

Please help me to achieve and where R2_ISP2 should be connected in the diagram to achieve the above rule.

Please let me know if my question is not clear.

Thanks in advance
