The bonded Site-to-Site VPN can detect routing failures on the path between two sites over each WAN con-
nection. Failed WAN connections will not be used to route VPN traffic. Health check packets are sent to the
peer to detect any failure. Checking the status more frequently leads to a shorter detection time, but higher
bandwidth overhead will be consumed.
Note
The BD1000 Site-to-Site VPN feature uses TCP and UDP port
32015 for establishing VPN connections. If you have a firewall in
front of the devices, you will need to add firewall rules for these ports
and protocols that will allow inbound and outbound traffic to pass
through the firewall.
