ZyWALL USG Support Notes

1.3. Setting up Virtual Server

It‟s a common practice to place company servers behind the USG ZyWALL‟s

protection, and at the mean time, letting WAN side clients/servers accessing the

intranet servers. For example, the company may have mail server, which needs to be

able to be connect by internet mail servers and clients; the company may also have

web server, ftp server, etc, which all need to be accessed from internet. We should

configure Virtual Server rules to achieve these applications.

1.3.1. Network Scenario
