Can I use CiscoWorks ICM within a network containing firewalls? If so, what are special configurations I need to take care of?
A. Yes, you can use CiscoWorks ICM in a network containing firewalls. Let us consider a few scenarios here: Your server is behind a firewalled network, while your clients are outside the firewall. In this scenario, you have to open ports on the firewall for your clients. •If you are interested in only CiscoWorks ICM, you must open TCP 1741 (or whichever port cscoweb is set to) as well as all established TCP connections. •If you require client support for Campus Manager, ACLM, or IPM, you have to consider CORBA which requires you to open all TCP ports above 1023 on your firewall. In such a case, a better solution would be to create VPN tunnels for your clients. You want to manage devices outside a firewall. In this scenario, you need to open a few ports. For maximum manageability, ensure that the ports listed in Table 4-2 are open.
