Thank you for the warm welcome. I appreciate the active healthy community. I have the tendency to just watch/read community post but do pitch in my .02 cents once in a while if I can...and I also ask for help at times when hitting the wall.
Philippine-based IT person with over 10years experience here on mostly MS Windows environment. I had few linux experiences but not that extensive. Have deployed Untangle, ClearOS, Zentyal and pfSense in my employments. Like a number of people here, I did liked Zentyal because of its (previous) vast feature-set but the recent direction seems to focus on being an SBS/Exchange-replacement (as they always banner it).
In my knowledge in linux are mostly Ubuntu-based.
Presently, we have we have 2 Zimbra servers which are running w/o backup (nor configured for high-availability/replication). Needless to say, we are running dangerously an old Zimbra (7.1.3) on OS which is reaching/has reached EOL (Ubuntu 10.04) 500 GB and 175 GB consecutively.
I am thankful I did find NethServer and it seems promising. I will be testing it soon (tomorrow perhaps...a few hours from now).
I would like to ask if collaboration feature (SOGo) supports such large data-store and mailbox (the largest presently is 30GB). Additionally, does the backup feature effectively backs-up (and restores) SQL, mailboxes, LDAP, etc.
On other fronts, I hope it will be easy to configure VLAN (with inter-VLAN-routing), VPN (openVPN and IPSEC), Proxy (transparent with HTTPS filtering...not available in other UTMs easily).
