Hello Forum Users,  
I have installed SLES15SP1 .  
Below rule in iptables is causing the slptool to fail in detecting the services of other hosts.  
REJECT all – anywhere anywhere reject-with icmp-host-prohibited  
I deleted it by using below command  
iptables -D INPUT -j REJECT --reject-with icmp-host-prohibited  
and slp started working with firewall enabled.  
however when i reload the firewalld it again went back to original rule (REJECT)  
how can i add this rule permanently so that even after reoading firewall it does not go back to default.

Use Yast2 - firewall (=\> firewalld; not recommended) for firewal rulesets configuration or “do it your self” (recommended):
