[syslog-ng] Syslog-ng not receiving messages

We had a old syslog-ng server which was completely configured and working
fine which died. I am using the same IP address so I can confidently say
that firewall is open and all the messages are arriving at the new server.
syslog is writing messages to the destination but the messages coming on
udp/tcp 514. I am trying to get it to write to one file and if that works
then to filter all the messages later by host.
I have attached the tcpdump output here and see info, debug messages making
it to this server
