Здравствуйте! Сложилась такая вот ситуация: у меня есть адсл-роутер, его внутренний ИП - 192.168.1.1. Есть 2 сетевых интерфейса: re1 - к нему подключен роутер, re0 - идет на сеть, его ИП - 72.207.1.148, так вот сам вопрос. Как нужно сконфигурировать устройства и вообще систему, чтобы раздавать инет юзерам по сети?

Дальше я выложил файл настроек, но так настроить у меня не получилось. В чем собственно проблема - понять не могу, инета даже на этой машине (сервере) нету, НАТ я возможно и неправильно настроил, но суть пока что не в єтом, на машине, к которой роутер подключен даже инета нету, НАТ думаю смогу настроить.

Вот файл rc.conf

amd_enable="YES"
gateway_enable="YES"
hostname="k.kanivnet"
ifconfig_re0="inet 72.207.1.148  netmask 255.255.0.0"
apachectl_enable="YES"
inetd_enable="YES"
linux_enable="YES"
nfs_client_enable="YES"
rpcbind_enable="YES"
sshd_enable="YES"
usbd_enable="YES"
hostname="k.kanivnet"
ifconfig_re1="inet 192.168.1.1  netmask 255.255.255.0"
ipv6_enable="YES"
defaultrouter="192.168.1.1"
hostname="k.kanivnet"
# NATD
gateway_enable="YES"
firewall_enable="YES"
firewall_type="OPEN"
natd_enable="YES"
natd_interface="re1"

Вродь все описал. Спасибо.

Насчет внешнего ипа - у меня он динамичный:) Как тогда быть?

Вот содержание файерволла:

rc.firewall

# Suck in the configuration variables.

elif [ -r /etc/rc.conf ]; then
 . /etc/rc.conf

# Define the firewall type in /etc/rc.conf.  Valid values are:
#   open     - will allow anyone in
#   client   - will try to protect just this machine
#   simple   - will try to protect a whole network
#   closed   - totally disables IP services except via lo0 interface
#   UNKNOWN  - disables the loading of firewall rules.
#   filename - will load the rules in the given filename (full path required)

# For ``client'' and ``simple'' the entries below should be customized

не понимаешь - не делаешь.

Разбирать твои логи из-за твоей лени, тратя собственное время - не мой подход.

За основу можешь взять вот это: http://bardak.blood.ru/work/freebsd/router.htm

 

Дальше по манам http://www.freebsd.org/cgi/man.cgi

Плотнее знакомься по ходу с http://www.freebsd.org/doc/ru_RU.KOI8-R/books/handbook/ ...

 

Формулируй вопросы по примеру: "Как обрезать входящую скорость по IP в ipfw?" (Предварительно воспользовавшись поиском по форуму, вдруг такой вопрос уже кто-то задавал ранее?)

 

Итак, пища к размышлению предоставлена, дерзай...

Почитал  rc.conf поплакал  )))

 

особенно с этого:

 

ifconfig_re1="inet 192.168.1.1  netmask 255.255.255.0"

Вообще-то я попросил помочь, раз все такие умные, то в чем причина? Или сами как только родились, так сразу и все настроили?
