I have a cisco 2811 router with 1 inside and 1 outside Fast Ethernet connections.
I have a separate CLEAR WIMAX modem which i would like to use as a backup for my on site SBS email server (currently mail is delivered through the CISCO router to the email server).
I am an active CCIE. I've done numbers of similar configurations for my clients in the past to provide WAN redundancy. Would like to build long term relationship with my client and provide assistance as needed basis.
