I purchase a RV325 in November of 2018. I am having a problem in that the unit randomly stops responding. I have upgraded to the latest firm ware update (January 2019) and that has not change the situation. When the RV325 stops responding on the internet, I can ping the unit, but I can not log on to the unit using a browser or putty. The only way I can clear the unit is to power off, wait 10 seconds and then power on. I have two internet connections, hence the dual WAN. But I am using one as primary and the other as a backup. Both WAN connections are broadband. I am also using it in gateway mode. I do not have a VPN in use. I am using static ip addresses and the ACL is the default configuration. I look in the logs and there are no entries.
