Depending on what interface your Cisco WAP is on, you may need to add the proper firewall rules on that interface in pfSense. The default rules for the LAN are usually "allow all in" on the interface, but other interfaces or VLANs you create would not have that same default. So you would need to explicitly allow the syslog-ng traffic.

I've never used the syslog-ng package on pfSense, but there may also be some security settings within the package that you need to adjust in order to allow remote devices (your Cisco WAP, for example) to log to the service.

@oleg-blecher said in syslog-ng not starting:

Undefined symbol "g_ptr_array_find_with_equal_func"

if you have that error after the update it means that everything was not successful

try from console

pkg install --force glib-2.56.3_7,1

or backup your config and do a clean install of 2.4.5 and restore

that error it's due to a mismatch between lib and syslog-ng
