Hi @ all
Since I made the Update from 8.309 to 8.310 on an ASG220 HA (active-passive) System, the Firewall drops traffic from its own public IP to 46.51.176.142 (AMAZON-EU-AWS) or 184.72.39.13 (AMAZON-EC2-7) on TCP Port 3400 constantly.
10:40:51 Default DROP TCP [public IP]:51370 → 46.51.176.142:3400 [SYN] len=60 ttl=64 tos=0x00 srcmac=[MAC]
[resolved]
The issue resolved itself... After the update there was no connection to a RED-Testsetup (the "RED server" on Node 2 was not running and constantly restarting ... and flooding my mailbox) , therefore I turned the RED service off. After an exchange of Node 2 (old Astaro220 to Sophos220) I got the issue described at the beginning. It stopped after restarting the RED service (I assumed a relation because of TCP Port 3400 and disabling of Up2Date/Pattern service had no effect) on the System. Therefore no issue just information. My contribution to this great forum.
