I have a LAN server version of NOD32 and I have set up a local update mirror. The five clients are configured to access updates over HTTP on the LAN. There's something that's not too clear on how updating is intended to work regarding the user name and password. For all NOD32 clients, the user name and password fields on the NOD32 client are blank, since they connect to the mirror on the LAN directly (that's how I understand it). If they need to update while on the Internet (off the company LAN), is the idea that I would have to open up a port in the firewall to let the update traffic in, or am I supposed to use the same LAN server user name and password on all NOD32 clients?
