Я думаю от версии это конечно не завист Smiley Стоит Ubuntu 6.10 Server НА машине две сетевый, одна смотрит в Инет, другая в локалку. Требуется получать доступ из внешней сети в локалку. т.е. нужен VPN сервер. Поставил pptpd, вроде все настроил: конфиги:

less /etc/pptpd.conf

#

# Sample Poptop configuration file /etc/pptpd.conf

#

# Changes are effective when pptpd is restarted.

###############################################################################

# TAG: ppp

# Path to the pppd program, default '/usr/sbin/pppd' on Linux

#

#ppp /usr/sbin/pppd

# TAG: option

# Specifies the location of the PPP options file.

# By default PPP looks in '/etc/ppp/options'

#

option /etc/ppp/pptpd-options

# TAG: debug

# Turns on (more) debugging to syslog

#

debug

# TAG: stimeout

# Specifies timeout (in seconds) on starting ctrl connection

#

# stimeout 10

# TAG: noipparam

# Suppress the passing of the client's IP address to PPP, which is

# done by default otherwise.

#

#noipparam

# TAG: logwtmp

# Use wtmp(5) to record client connections and disconnections.

#

#logwtmp

# TAG: bcrelay <if>

# Turns on broadcast relay to clients from interface <if>

#

#bcrelay eth1

# TAG: localip

# TAG: remoteip

# Specifies the local and remote IP address ranges.

#

# Any addresses work as long as the local machine takes care of the

# routing. But if you want to use MS-Windows networking, you should

# use IP addresses out of the LAN address space and use the proxyarp

# option in the pppd options file, or run bcrelay.

#

# You can specify single IP addresses seperated by commas or you can

# specify ranges, or both. For example:

#

#

# 192.168.0.234,192.168.0.245-249,192.168.0.254

#

# IMPORTANT RESTRICTIONS:

#

# 1. No spaces are permitted between commas or within addresses.

#

# 2. If you give more IP addresses than MAX_CONNECTIONS, it will

# start at the beginning of the list and go until it gets

# MAX_CONNECTIONS IPs. Others will be ignored.

#

# 3. No shortcuts in ranges! ie. 234-8 does not mean 234 to 238,

# you must type 234-238 if you mean this.

#

# 4. If you give a single localIP, that's ok - all local IPs will

# be set to the given one. You MUST still give at least one remote

# IP for each simultaneous client.

#

# (Recommended)

localip 192.168.1.1

#remoteip 192.168.1.2 # or #localip 192.168.0.234-238,192.168.0.245 #remoteip 192.168.1.234-238,192.168.1.245 ________________________________________________________________________________ ___________________

# Authentication

# Name of the local system for authentication purposes # (must match the second field in /etc/ppp/chap-secrets entries) name pptpd

# Network and Routingless /etc/ppp/chap-secrets

# If pppd is acting as a server for Microsoft Windows clients, this # option allows pppd to supply one or two DNS (Domain Name Server) # addresses to the clients.

# Add an entry to this system's ARP [Address Resolution Protocol] # table with the IP address of the peer and the Ethernet address of this # system.

и прописал логин и пароль в less /etc/ppp/chap-secrets внутренняя сетка 192.168.1.0/24

Так вот, из внешней сети подключаюсь, выдается IP, вроде как все ОК. Могу пингать удаленный конец, сетевух которая смотрить в локалку, а вот саму локалку не вижу Sad

В чем проблема не могу понять Подскажить кто как делал. на фаерволе все открыто может что-то надо в фаерволе прописать, чтобы он пакеты перекидывал и ppp0 на локальную сетевуху. Заранее спасибо.

Нет в фаерволе ничего не надо прописывать.

Вот так всегда, стоит запостить вопрос, так сразу нахожу решение.

Надо было всего лишь сделать - echo 1 > /proc/sys/net/ipv4/ip_forward ну или

enable IP forwarding in /etc/sysctl.conf: net.ipv4.ip_forward = 1

Re: VPN сервер на Ubuntu 6.10

В винде файрвол это бронесковородка чтобы дырку в жопе прикрывать. В линуксе его функциональность чуть шире. Я препдоложил что надо NAT поднять на интерфейс. Что делается через iptables, который в свою очередь - файрвол.
