I have a ASG220 and configured a second WAN interface that was working fine using a policy route for mail traffic, but we started having issues with the primary WAN connection, so I changed it to a standby interface to backup the primary when it goes down.. however the standby interface now just shows an error status and does not seem to work for failover.. I tried to switch it to a different physical interface, but it did not help.. Any ideas?
