Update: The problem doesn't occur when client is connected through vpn. Now how is that possible?

Installation and Upgrades / Gmail connection DROP
« on: November 25, 2020, 02:50:50 pm »
Hi,
I have issues with gmail on some workstations saying that there is no web connection or can't send email. Meantime google chat works fine. This happens sometimes like it was some king of flood protection in Zentyal (we are using gmail on number of workstations simultaniously). I have no firewall rule that blocks outbound 443, I even added special rule to allow to connect from LAN to any destination on Http and HTTPs (on top of stanrdard any/any/any in internal networks). I do not use http proxy.
I have some dropped TCP packets from IP 172.217.16.5 (that's google's if I'm right) to local gateway, source port 443, destination 64429 but is that it? Correting me if I'm wrong but adding a rule allowing all trafic from 443 is not a good idea?

Directory and Authentication / [Question] 2x Wan, Send traffic only through one. Use second only as backup.

Hi,
I have 2x Wan on eth1 (Main) and eth3 (Backup). I want to send all traffic trought 1 unless connection fails.
With:
1. Disabled traffic balancing
2. Gateways for traffic balance - selected only Main
3. Multigateways rules - interface any/source any/ destination any/service any/gateway Main
I can't ping thorugh Backup
with:
1. Disabled traffic balancing
2. Gateways for traffic balance - selected Main and BACKUP
3. Multigateways rules - interface any/source any/ destination any/service any/gateway Main
I can ping from both Main and Backup but traffic balancing seems to be working randomly and it send traffic trough both gateways.
I've also setup enabled failover ping to gateway.
What I'm doing wrong? I don't want traffic balancing I want all traffic to go through Main untill it fails then switch to backup.
