Re: firewalld configuration for EPICS?

Minor comment:

Channel Access uses port ca-2 (5065) only for beacon messages which are UDP, so it is not really necessary to open ca-2/tcp.

Hi Dirk,

you could use the following as a EPICS.xml under /etc/firewalld/services

<?xml version="1.0" encoding="utf-8"?>
<service>
  <short>EPICS Channel Access service</short>
  <port port="ca-1" protocol="tcp"/>
  <port port="ca-1" protocol="udp"/>
  <port port="ca-2" protocol="tcp"/>
  <port port="ca-2" protocol="udp"/>
  <source-port port="ca-1" protocol="tcp"/>
  <source-port port="ca-1" protocol="udp"/>
  <source-port port="ca-2" protocol="tcp"/>
  <source-port port="ca-2" protocol="udp"/>
</service>

And then select EPICS for the zone you need to enable the ports.

Regards,

Jörn
