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 below
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 delete this rule permanently so that even after reoading firewall it does not go back to default.
i tried using iptables-save and iptables-restore but after the firewalld restart it again siwtch to the default.

Hello bspteam00,

I am certainly no expert (I am still using IPTables at the moment until I have the time to spend reviewing FirewallD) but from the blurb that I have read myself it is recommended not to have both IPTables and FirewallD running simultaneously for a whole host of reasons - A quick "google" on your part will reveal this.
