Hi

Does anyone already have a firewalld configuration to allow Channel
Access? I.e. something like a /usr/lib/firewalld/services/epics.xml file?

Dirk

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
