I'm brand new here so sorry if this has been asked before

I'd like to set up a Multi-Wan router for my 5 system network that connects via WiFi to (for example) my iPhone's mobile hotspot or equivalent Verizon hotspot using a USB WiFi adapter on my Linux box, as well as to one or two wired broadband modems (for example, CenturyLink and Comcast)

Primary purpose is for my network to have connectivity when one (or both if have more than one) of the wired links drop. Speed gain would be nice but secondary to keeping e-mail running seamlessly to all the internal systems ( a couple of which are WiFi to an access point on my network, and the remainder go through 1Gb switches.) Also want to set up VPN access but this is also secondary to the objective of keeping e-mail running 24/7 for everybody.

Can I do this with ClearOS and an available app? I'm fine with paying for ClearOS Pro if necessary to get the functionality. Also no problem adding multiple Ethernet cards if need be.

Basically looking for a Yes/No answer. If it's yes I'll download Clear OS and figure out how to make it work.

Thanks much
