For example, could I specify: It's a global default; a more specific interface name that comes with an address will override it. So you could do what you drafted below. The entire "ifconfig" feature in rc.d/jail does not really belong there but people started using it after it was introduced so we lost that race. > jail_squid_interface="bge0" > jail_squid_ip="192.168.177.62/32" > jail_squid_ip_multi0="192.168.177.63/32" > jail_squid_ip_multi1="em0|192.168.177.62/32" > > Below is a patch against HEAD to document the $interface|$ip syntax. That wasn't done on purpose; man rc.conf has it, if you lookup jail_<jname>_ip . /bz -- Bjoern A. Zeeb It will not break if you know what you are doing.
