<strong>Trend</strong> Micro <strong>OfficeScan</strong> <strong>10.6</strong> Administrator’s <strong>Guide</strong><br />

Most of these limitations can be overcome by setting up a dual-stack proxy server that<br />

can convert between IPv4 and IPv6 addresses (such as DeleGate). Position the proxy<br />

server between the <strong>OfficeScan</strong> clients and the entities to which they connect.<br />

Configuring IPv6 Addresses<br />

The web console allows you to configure an IPv6 address or an IPv6 address range. The<br />

following are some configuration guidelines.<br />

1. <strong>OfficeScan</strong> accepts standard IPv6 address presentations.<br />

For example:<br />

2001:0db7:85a3:0000:0000:8a2e:0370:7334<br />

2001:db7:85a3:0:0:8a2e:370:7334<br />

2001:db7:85a3::8a2e:370:7334<br />

::ffff:192.0.2.128<br />

2. <strong>OfficeScan</strong> also accepts link-local IPv6 addresses, such as:<br />

fe80::210:5aff:feaa:20a2<br />

WARNING! Exercise caution when specifying a link-local IPv6 address because<br />

even though <strong>OfficeScan</strong> can accept the address, it might not work as<br />

expected under certain circumstances. For example, clients cannot<br />

update from an update source if the source is on another network<br />

segment and is identified by its link-local IPv6 address.<br />

3. When the IPv6 address is part of a URL, enclose the address in parentheses.<br />

4. For IPv6 address ranges, a prefix and prefix length are usually required. For<br />

configurations that require the server to query IP addresses, prefix length<br />

restrictions apply to prevent performance issues that may occur when the server<br />

queries a significant number of IP addresses. For example, for the Outside Server<br />

Management feature, the prefix length can only be between 112 (65,536 IP<br />

addresses) and 128 (2 IP addresses).
