Opening port on XenServer 8

[Ingo Kalker]

Hi,

 

did someone find a way to open a specific port (Zabbix agent) on XenServer 8?

 

The instructions for version 7 are not working anymore. Every time I try to save and reload the modified /etc/sysconfig/iptables file via

 

# service iptables save && service iptables restart

 

my modifications are being overwritten by a default rule set.

 

Thanks.

Since XS 7.X is based on CentOS 7, it may be using firewalld instead of iptables. See for example: https://www.tecmint.com/start-stop-disable-enable-firewalld-iptables-firewall/

However, I believe iptables still should work under XS 7.X. See this thread about a XS 7.X firewall issue: https://discussions.citrix.com/topic/379475-xenserver-70-firewall/
