I have a site to site vpn using dsl that is fairly reliable.  When it does quit, is supposed to failover to a 2.4 radio link that drops about 1 in 40 to 50 packets.  What can I do to make it switch?

    Hi @Jimbo,

    Welcome to Zyxel community 😁

    Can you provide your network topology and scenario expectation behavior.

    I was a little bit confused about the VPN failover to 2.4 radio.

    Sure, I am connecting to a remote office over an IPSec VPN with a pair of USG110. THe primary link is over DSL that is on WAN 1 of each firewall and the radio link is connected to WAN2 on each side. Both the local and remote subnets are Class C addresses. THe DSL goes out, the radio doesnt pick up. the gre tunnel address is used as the connecttivity check and it pings but not at 100%
