Fix EPICS role with Firewall at CS
CSS does not behave right due to firewall issues.
Setup: CS + ANKA-VPN
Problem:
PVs are not shown as connected, though caget
works.
Workaround:
sudo firewall-cmd --add-port=5064/udp --permanent
sudo firewall-cmd --add-source-port=5064/udp --permanent
sudo systemctl reload firewalld
Ideas for better fixes: Add ANKA-VPN to internal-zone. Or do a similar thing to the iptables rule:
iptables -I INPUT 1 -m state --state ESTABLISHED,RELATED -j ACCEPT
