One router goes to the corporation email server and another one goes to the Internet
Symptoms: you have one router connecting to the corporation for email and the Internet access. However, the corporate Proxy server filters web sites and watches you access. Then, you add another router for the Internet access and want to use the corporate router for the email only, but the traffic always go to the corporation router.
Resolution: You need to modify the routing table. Make all traffic go to the Internet and point the email server to the corporation ip range.
