netmap - Shorewall NETMAP definition file
This file is used to map addresses in one network to corresponding
addresses in a second network.
To use this file, your kernel and iptables must have NETMAP support
The columns in the file are as follows.
TYPE - DNAT|SNAT
Must be DNAT or SNAT.
If DNAT, traffic entering INTERFACE and addressed to NET1 has its
destination address rewritten to the corresponding address in NET2.
If SNAT, traffic leaving INTERFACE with a source address in NET1
has it's source address rewritten to the corresponding address in
NET1 - network-address
Network in CIDR format (e.g., 192.168.1.0/24).
INTERFACE - interface
The name of a network interface. The interface must be defined in
shorewall-interfaces(5). Shorewall allows loose matches to
wildcard entries in shorewall-interfaces(5). For example, ppp0
in this file will match a shorewall-interfaces(8) entry that
NET2 - network-address
Network in CIDR format
