HP-UX IPSec version A.02.01 Administrator's Guide

Configuring HP-UX IPSec
Using ipsec_config
Chapter 4 97
The default source address parameter values in
/var/adm/ipsec/.ipsec_profile are 0.0.0.0/0/0 (IPv4 address
0.0.0.0, address prefix length 0, port 0). This matches any IPv4 address
and any port number. In most topologies, this is appropriates since the
default source (local) address will be any IPv4 address on the local
system.
IPv6 Networks If you have a network that primarily contains IPv6
addresses, you can change the source parameter value to match any
IPv6 address and any port number (0:0/0/0) in the HostPolicy-Defaults,
GWPolicy-Defaults, and TunnelPolicy-Defaults sections of the profile file.
You can also change the remote parameter value in the
IKEPolicy-Defaults section to match any IPv6 address (0::0/0).
Multihomed Nodes with Private Interfaces If the local system is
multihomed with one public IP interface and one or more private IP
interfaces, you may want to secure only the one public IP interface. In
this case, you can set the default source parameter value to the address
of the public IP interface in the HostPolicy-Defaults, GWPolicy-Defaults,
and TunnelPolicy-Defaults sections of the profile file.
Dynamic Configuration Updates
The ipsec_config utility dynamically updates the configuration
database. If HP-UX IPSec is running, ipsec_config also updates the
runtime IPsec policy database, and runtime IKE configuration data (IKE
policies and authentication records).
Dynamic Deletions
If you delete an object while HP-UX IPSec is running, HP-UX IPSec
deletes it from its runtime database. If you delete an IPsec policy, HP-UX
IPSec deletes any associated IPsec SAs. If you delete an IKE policy,
HP-UX deletes any associated IKE SAs. IPsec SAs negotiated using the
IKE SAs may continue to operate, but IKE peers will be unable to send
control messages for the affected IPsec SAs.
nocommit Argument
The nocommit argument validates entries but does not update the
configuration and runtime databases. The nocommit argument is illegal
inside batch files (you cannot specify the nocommit argument as part of a
statement inside a batch file). You can specify the nocommit argument as
