Looking for a way to setup 2 ISPs in failover mode, for both incoming & outgoing traffic, for our small (<100 devices) network.

The leading contender for now seems to be the Peplink Balance 310. However, a reseller I spoke with said it's great for 100% outgoing connectivity, but didn't seem to be confident in its abilities to handle incoming traffic. This is important as we host our own web site, Exchange e-mail, and virtual desktops (RDP).

Do any Peplink owners use this for failover of incoming traffic?

Are there other devices I should be considering? We're currently using a Cisco 1800 series router & ASA 5500 series firewall, with Comcast & T-1 lines (the goal being to replace the T with DSL/FiOS {whenever that becomes availble}).

Price range: ~$1000 - $2500 USD.

Thanks.
