[syslog-ng] Weird issue with remote syslog-ng setup

Hi, I'm running into a weird issue where I have syslog-ng running on a client and server. Both are correctly configured to push log files from the client to the server and they're both Linux boxes. A netstat command on the client shows an established connection from the client to the server, however on the server, a netstat command does not show a connection from the server to the client or client to server. I checked firewall settings in iptables, however nothing seems to be working. Any ideas on how I can troubleshoot this? Sincerely,
