Currently, I am using IPSec VPN to connect 2 China offices back to HQ and all traffic are routed back to HQ, including Internet Surfing. As such, bandwidth in HQ is always at Peak.
Speedfusion caught my attention and I intented to leverage on multiple DSL circuits instead of upgrading my current bandwidth.
However, as a newbie, there a few grey areas which I’m not sure.
Attach diagram for easy reference, on the left is HQ and right are the 2 China offices.
-HQ, Peplink 580, drop-in mode, require static route to firewall
-China, Peplink 210, replacing existing firewall
Can speedfusion works behind Great China Firewall?
Can China offices’ internet traffic routed via speedfusion tunnel to HQ and filtered by my Barracuda Web Filtering before going out to WWW?
In HQ, does normal internet surfing benefits from Multi WAN load balance?
With Multi WAN bonding, does this affect my Web hosting and in/out email traffic?
Any changes requires on my DMZ segment?
In drop-in mode, on Peplink 580, the internal facing port, my firewall should treat it as WAN or LAN?
