To open port of firewall you need to take into account operations that you plan to use. For access to ILO and remoted console as well as virtual media the following ports are needed:
Web (non-SSL) 80
Remote Console 17990
Virtual Media 17988
Full set of ports is more extensive:
ILO FUNCTION SOCKET TYPE PORT NUMBER ---------------------- ----------- ----------- Secure Shell (SSH) TCP 22 Remote Console/Telnet TCP 23 Web Server Non-SSL TCP 80 Web Server SSL TCP 443 Terminal Services TCP 3389 Virtual Media TCP 17988 Shared Remote Console TCP 9300 Console Replay TCP 17990 Raw Serial Data TCP 3002

You can look up what ports are used via the iLO 3 web interface. Expand the "Administration" menu on the left, then click on the "Access Settings" link. That screen will tell you the ports used by the various services.
Here are the defaults:
Web (non-SSL) 80
Remote Console 17990
Virtual Media 17988
You might also need to enable other ports if you're using DHCP, DNS, SNTP, SNMP, and/or LDAP from iLO.
For an iLO device to work properly when going across routers using port blocking and/or firewalls, ports 23, 80, 443, and 17988 must be open.
The directory services LDAP port (636) may be required. The Terminal Services RDP port (3389) may be required.
Port 23 is for the Telnet ports where the remote and graphical Remote Console is used, port 80 is for HTTP communications, port 443 is required for the HTTPS connection, and port 17988 is for Virtual Media.
LDAP traffic from a directory server uses random port numbers to enter the iLO device.
The inability to access the iLO management ports is often confused with incorrect proxy settings. When in doubt, disable proxy in Internet Explorer or Netscape.
We have found that the remote console port defined for iLo3 has changed from being 3389 (standard RDP port) to 17990.
Can one of you please ask HP about the reasoning about this change and if it will be an issue if we change this to the standard 3389 port. The alternative is that we get NS to open the port 17990 on the firewall then we do not have to manually change every iLO 3 interface for servers in ecom.
I think they're confusing 2 different things. Port #3389 is a standard RDP port and was valid for the "iLO Terminal Services Pass-through" but never was the port for accessing the iLO remote console. Since TS Pass-through is no longer available with iLO3, this doesn't apply.

If you want to access an iLO behind a firewall, there are some TCP ports that need to be opened on the firewall to allow all iLO traffic to flow through. Here is a list of the default ports used by iLO, but these can be modified on iLO's Administration… Access… Services… tab.ILO FUNCTION SOCKET TYPE PORT NUMBER ---------------------- ----------- ----------- Secure Shell (SSH) TCP 22 Remote Console/Telnet TCP 23 Web Server Non-SSL TCP 80 Web Server SSL TCP 443 Terminal Services TCP 3389 Virtual Media TCP 17988 Shared Remote Console TCP 9300 Console Replay TCP 17990 Raw Serial Data TCP 3002
