I am exploring the possibility of installing a PepLink 310 for an office with 2 WAN circuits. We have 2 IPSEC VPN tunnels on our firewalls I would like to continue using because or firewall provides for detailed polices to manage access. I see the Peplink only will pass through 1 VPN tunnel in the services IPSEC Passthrough. We are only interested in balancing our Internet traffic wit the Peplink. Would leaving my firewalls (HA) with public addresses and allowing the VPN tunnels from the firewall directly and then forwarding my Internet traffic to the Peplink for balancing over the 2 circuits be a viable configuration? How will the Peplink detect the VPN traffic on the links when it calculates utilization.
Also playing around with the live demo on the website I did not see anywhere I could control the balancing algorithm used or how the circuit bandwidth/capacity is defined?
