11. IP and network management#

This chapter describes how IP addresses for computer systems in a UCS domain can be centrally managed via UMC modules and assigned via DHCP.

Network objects bundle available IP address segments of a network. The DNS resolution as well as the assignment of IP addresses via DHCP are integrated in UCS, as detailed in Administration of DNS data with BIND and IP assignment via DHCP.

Incoming and outgoing network traffic can be restricted via the Univention Firewall based on iptables, see Packet filter with Univention Firewall.

The integration of the proxy server Squid allows the caching of web contents and the enforcement of content policies for web access, see Web proxy for caching and policy management / virus scan.
