Chapter 24 Security Policy The following table describes the labels in this screen. Table 204 Configuration > Security Policy > Session Control LABEL DESCRIPTION General Settings UDP Session Time Out Session Limit Settings Enable Session limit IPv4 / IPv6 Configuration Default Session per Host Set how many seconds the Zyxel Device will allow a UDP session to remain idle (without UDP traffic) before closing it. Select this check box to control the number of concurrent sessions hosts can have. This table lists the rules for limiting the number of concurrent sessions hosts can have. This field is configurable only when you enable session limit. Use this field to set a common limit to the number of concurrent NAT/Security Policy sessions each client computer can have. If only a few clients use peer to peer applications, you can raise this number to improve their performance. With heavy peer to peer application use, lower this number to ensure no single client uses too many of the available NAT sessions.
