CIP iptables/ip6tables Support (climiptables)
For CLIMs with MULTIPROV ON, each provider has its own iptables/ip6tables configuration, which
can be independently manipulated and disabled or enabled.
The CIP implementation of iptables/ip6tables only supports the INPUT chain of the ‘filter’ table. In
addition, CIP does not directly support invoking the Linux iptables/ip6tables through CLIMCMD.
Rather, CIP wraps these commands with similar iptables/ip6tables commands in climconfig. These
wrappers allow the CIP software to preserve similar iptables syntax while allowing CIP software
to:
1. Use iptables/ip6tables internally. CIP software filters out iptables/ip6tables commands that
are in conflict with CIP internal rules. The CIP rules are used during failover and to control the
dedicated service LAN IP traffic.
2. Provide automatic configuration persistence. The CIP software persists the iptables/ip6tables
configuration across CLIM boots and HP CLIM software restarts.
3. Provide configuration backup and restore. CIP software has a provision for allowing customers
to backup and restore the configuration of a CLIM, including the iptables/ip6tables
configuration.
4. Ensure that the exposed iptables/ip6tables functionality is conforming to the ways the CLIM
is used in the CIP environment. This involves removing the support for some functionality,
mostly related to router functionality which is not supported by the CLIM.
CIP iptables/ip6tables depends on Linux iptables/ip6tables. Functionality changes in subsequent
versions of Linux iptables/ip6tables may affect the functionality of CIP iptables/ip6tables.
