Logging to cPanel/WHM server
-
Hello,
Right now, I have our pfSense hardware device connected to a switch on the WAN interface, with a single cPanel server connected to the switch. The pfSense LAN interface isn't connected to anything yet, we need to get another switch for that. Yesterday pfSense died (no VPN, no access to servers, etc), but after restarting it I couldn't see anything in the logs, but I noticed that I could send the logs to another server. The cPanel server is running CentOS 7.2.
I'm having a hard time getting this to work. I don't want to interfere with the local logs on the other server, I just want to allow it to accept and save the pfSense logs also.
On the pfSense settings page for the logs, for the source address I've tried any, WAN, and DMZ. I use IPv4, enter the WAN IP of the cPanel server, and check the boxes for system and firewall events. When I chose any or DMZ, I didn't see anything, but when I chose WAN I did see those packets on UDP 514 getting blocked, so I added a pass rule for them. I'm still not seeing anything saved on the cPanel server though.
On the server, I'm using the following for rsyslog.conf. I uncommented the UDP module and filled in those settings, and added the 3 if statements at the top of the rules section (I added the LAN IP of pfSense even though I know that's not going to work yet):

Does anyone know what I'm doing wrong?
Thanks

I've been able to use tcpdump to verify that the server is receiving traffic from pfSense, but I'm still not able to get it written to a file. This is what I've got in the rsyslog.conf file (I've changed the first 3 octets in the IP, and I removed the other rules that wouldn't match):

This is becoming a critical issue for us, can anyone tell what I've got wrong?
