I have disabled iptables:
[3:26 PM, 4/18/2019] Abed Abd Elhai: iptables --list
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
And also the firewalld
service firewalld status
Redirecting to /bin/systemctl status firewalld.service
● firewalld.service
   Loaded: masked (/dev/null; bad)
   Active: inactive (dead)

I don’t have access to the vcenter, is there anything that I can check within the server?
When the server receives a accounting message I see it in tcpdump and also in radsniff but not in the radiusd -X terminal.
However when I run a test with radtest or radwho I do see the message in the radiusd terminal.


can you show the networking that you have done for making the vm network
reachable to outside network ?
