Port 23 and iLO4 Access Through Firewall

Port 23 and iLO4 Access Through Firewall

Does Port 23 really need to be open in order to access an iLO4? 

 

For iLO2 and iLO3 we always had Port 23 open through our firewalls and the documentation for iLO4 indicates that Port 23 should be allowed.  Having Port 23 open has always caused our security folks heartburn so they asked me to test it to verify that it is still required for iLO4 on our DL 360P Gen8 servers.

 

I configured a rule to allow only ports 22, 80, 443, 17988 and 17999 in our Juniper Firewall and everything seems to be working just fine.  With those ports open, I was able to connect to the iLO using HTTP and HTTPS, open a remote console session, connect and view files via Virtual Media and open an SSH session using PuTTy.   Seems like when I tried this using iLO2, I was able to connect to the iLO but could never get the remote console to connect unless Port 23 was open but that was a long time ago.

 

Has any one else tried this and got it to work without Port 23 open?

 

Any idea why the iLO4 documentation still seems to indicate that Port 23 should be open?

 

Thanks.
