|
|
# Note: Current versions of FreeBSD all call /etc/rc.firewall
|
|
# BEFORE running named, so if the DNS server and NAT are on the same
|
|
# machine, the nameserver won't be up if natd is called from /etc/rc.firewall

|
|
# Static NAT address mapping:
|
|
#
|
|
# ipconfig must apply any legal IP numbers that inside hosts
|
|
# will be known by to the outside interface. These are sometimes known as
|
|
# virtual IP numbers. It's suggested to use the "interface" directive
|
|
# instead of the "alias_address" directive to make it more clear what is
|
|
# going on. (although both will work)
|
|
#
|
|
# DNS in this situation can get hairy. For example, an inside host
|
|
# named aweb.company.com is located at 192.168.1.56, and needs to be
|
|
# accessible through a legal IP number like 198.105.232.1. If both
|
|
# 192.168.1.56 and 198.105.232.1 are set up as address records in the DNS
|
|
# for aweb.company.com, then external hosts attempting to access
|
|
# aweb.company.com may use address 192.168.1.56 which is inaccessible to them.
|
|
#
|
|
# The obvious solution is to use only a single address for the name, the
|
|
# outside address. However, this creates needless traffic through the
|
|
# NAT, because inside hosts will go through the NAT to get to the legal
|
|
# number, even when the inside number is on the same subnet as they are!
|
|
#
|
|
# It's probably not a good idea to use DNS names in redirect_address statements
|
|
#
|
|
#The following mapping points outside address 198.105.232.1 to 192.168.1.56
|
|
#redirect_address 192.168.1.56 198.105.232.1
