We have HQ office and remote office A are connected via mpls network, each office get their own internet and ASA firewall. But now the office A has the need to upgrade their internet circuit so I want to temporarily redirect their internet traffic to use HQ office's internet. To accomplish that, I was thinking just simply change my gateway of last resort on Office A's ASA to the mpls router (in bridge mode, managed by ISP) and all traffic requests to the internet would be routed to HQ's office. Am I correct? Do I need to perform additional configure on either of the ASA or any other router?
At office A's ASA currently has this routing
route outside 0.0.0.0 0.0.0.0 72.252.151.1 1 --->172.252.151.1 is office A DSL internet modem
do I do this?
no route outside 0.0.0.0 0.0.0.0 72.252.151.1 1
route inside 0.0.0.0 0.0.0.0 172.16.30.1 1 --->172.16.30.1 is office A's mpls internal interface (this router currently route 0.0.0.0 0.0.0.0 to 172.16.30.2 which is office A's ASA inside interface
Any helps would be greatly appreciated!
