Has anyone else run into Kaseya's vPro implementation getting dropped as it returns to the VSA? We see the traffic coming and going from our lab firewall... where the vPro Proxy is, but we the see the return traffic getting dropped at our datacenter where Kaseya resides... I am scratching my head... we have even allowed all traffic from our lab's public ip to pass through to the kaseya server... but it still drops, firewall log shows it... funny thing is it recognizes the the traffic as custom service Kaseya-Agent-Checkin (5721... if i remember correctly), which is allowed, and clearly working for all agent checkins.  The directions give no indication anything is required on the firewall that Kaseya resides behind.  Obviously we already configured the vPro Proxy and its firewall side.
