https://community.hpe.com/t5/server-management-systems/sim-5-firewall-server-login/m-p/3741112#M18786 I am managing some servers that are behind a firewall. I opened all of the ports listed in the below document by HP Sim. SIM looks like it is recieving communication from the servers via ping, snmp, etc but when I click on the System management homepage it just times out and says The page cannot be displayed, Cannot find serer or DNS Error. Funny thing is if I type in the server I want to manage on my CMS Central Mngmt Server ie https://myserver:2381 I can get to it without a problem. Any ideas?<BR /><BR /><A href="http://h10018.www1.hp.com/wwsolutions/misc/hpsim-helpfiles/security5.pdf" target="_blank">http://h10018.www1.hp.com/wwsolutions/misc/hpsim-helpfiles/security5.pdf</A> Tue, 28 Feb 2006 14:56:13 GMT Andrew Knoke_1 2006-02-28T14:56:13Z https://community.hpe.com/t5/server-management-systems/sim-5-firewall-server-login/m-p/3741112#M18786 I am managing some servers that are behind a firewall.
