I just tested Integration of iView 3 in Sophos Firewall Manager 16.01 RC-1. This seems to work pretty well. When I add a Firewall to SFM, it gets created immediatedly also in iView.
Does anybody know which logfiles (on iView and on SFM Side) I have to check if anything goes wrong with Synchronization between SFM and iView? This question just for Documentation purposes.
