I am managing a network that doesn't have enough bandwidth to run their network.
They are quite remote and are currently using a 3G internet connection. Not ideal but it's all they have to work with.
I want to increase their internet bandwidth and was considering adding a second 3G modem to the network at the other end of the building and linking it into the network.
I'm wondering what's the best way to add a second internet connection and design the DNS so that I can group computers and hook them to separate modems to share the internet load. I was thinking like this: Group-A link to modem-A, Group-B link to Modem-B but keep them all on the same domain.
I have a Sonicwall TZ210 firewall and a 2008 SBS server in place.
I haven't setup dual internet connections before for bandwidth sharing and would like advice if this is the best way to go considering I only have 3G to work with (satellite and fiber are out of their budget unfortunately).
What do you guys think? Is this a good idea to go with a second 3G modem?
What would be the best way to link the client computers to separate modems?
