New to Balance (here a 310X), I see traffic going out from WAN2 interface while it is in standby state.
One oddity: among ICMP probes, the Balance tries to open a SSL session with second DNS server in settings.
While I can understand the ICMP probes, I am puzzled about SYN packets on port 443 sent to, in this case, 220.127.116.11.
A take on this to ask if there is a way to completely disable probes while the WAN interface is in standby. Is that possible ?
