I have just installed a graylog server and trying to add log sources one by one. By the way, I am a newbie at graylog.
I have configured my firewall (which is a Fortinet device) to send syslogs through 514. I did necessary iptables config on graylog server to direct 514 to 1514 and configured an input at graylog. (I tried both standard syslog and raw/plaintext udp )
When I check with tcpdump, I can see that logs are coming to the server.
However, these logs don’t appear in received messages.
Any ideas or additional config to make this work?
