HI Abu Salim, I could do that, but I am not firewall administrator, but could arrange and ask guy responsible for it to help with troubleshouting
Thank you for comment Kidn regards, Arlytex ---------- Forwarded message ---------- From: Abu Salim <[email protected]> Date: 2009/8/6 Subject: Re: [Nagios-users] Monitor Windows 2003 using nagios + SNMP To: arly arly <[email protected]> Cc: [email protected] Hi Arlytex One of the troubleshooting steps you can take will be to monitor the Live logs on your firewall, if it's a Cisco ASA firewall you can easily check on ASDM which port is getting blocked or if there is any access-list preventing the packet flow.
