Monitoring Firewall setup

[sth_bytelab]

Hi
We have just bought a new firewall and are in the middle of making all the policies.
I would like to check all these policies use NagiosXI.
Do you guys have any suggestions about how to do this?
I have thought about checking the TCP-connections on every hosts, but is there a smart or better way?

Thanks!

If your firewall allows for stateful connections, just allow all outbound from the nagios XI server and only established inbound. Otherwise, installation requires (http,https,ftp,and ssh):
port 21
port 22
port 80
port 443

For deployment an monitoring, the necessary ports all depend on which agents and check you are running . . .
