[EN] Tunnel traffic from VPN through Server to enable Internet Access and use Squid as Transparent Proxy

You want to create OpenVPN or PPTD-VPN enabled server with your VPN or Dedicated Server?
It’s not so hard to do it, heres the manual way (may be improved later to do it in an automatic way)

  1. Install pptpd-vpn as shown HERE
    • # apt-get install squidguard squid3 pptpd-vpn  openvpn
      • or OpenVPN as shown HEREI prefere pptpd-vpn as it’s really easy to setup!
  • Try to connect, but at the moment you wont be able to use the Internet until
    • script on the next Step has been executed (and then reconnect)
    • or you use the Proxy
    • do the next steps:
      # nano /root/

#TUN+ devices are used by OpenVPN
#TAP+ devices are used by PPP-VPN
# <- are Comments, leave it as is

# IP-Range i.e.: or or whatever

# CIDR Without / (Slash)
# Usally: is /24 with
# Usally: is /16 with
# Usally: is /16 with


#Primary Ethernet Card (Usally, Eth0)

# OpenVPN (Firewall Port Opening)
iptables -A INPUT -i $eth-nic -m state –state NEW -p udp –dport $OPVPN-PORT0 -j ACCEPT

# Allow TUN interface connections to OpenVPN server
iptables -A INPUT -i tun+ -j ACCEPT
iptables -A INPUT -i tap+ -j ACCEPT
# Allow TUN interface connections to be forwarded through other interfaces
iptables -A FORWARD -i tun+ -j ACCEPT
iptables -A FORWARD -i tun+ -o $eth-nic -m state –state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i $eth-nic -o tun+ -m state –state RELATED,ESTABLISHED -j ACCEPT

# Allow TAP interface connections to be forwarded through other interfaces
iptables -A FORWARD -i tap+ -j ACCEPT
iptables -A FORWARD -i tap+ -o $eth-nic -m state –state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i $eth-nic -o tap+ -m state –state RELATED,ESTABLISHED -j ACCEPT
# NAT the VPN client traffic to the internet
iptables -t nat -A POSTROUTING -s $NAT-NETWORK/$NAT-NETMASK -o $eth-nic -j MASQUERADE
iptables -A OUTPUT -o tun+ -j ACCEPT
iptables -A OUTPUT -o tap+ -j ACCEPT

# Pre-Route trough Proxy
# Support for OpenVPN and PPP-VPN
iptables -t nat -A PREROUTING -i ppp+ -p tcp –dport 80 -j REDIRECT –to-ports $PROXY-PORT1
iptables -t nat -A PREROUTING -i tap+ -p tcp –dport 80 -j REDIRECT –to-ports $PROXY-PORT2

echo done.

  • # chmod 700 /root/
  • # ./root/ #needs only to be runned on time per reboot.

The Reason why we use ppp+ and tap+ is, that we support more then one connection with this. I Also use 2 different Ports on Squid for having a easier handling, but you can also use the same ports.

3. Using the Proxy

On this Setup, i used PAM for Auth, this means that i prefer existing users on the System to auth against the Proxy.

  1. run the following commands after doing the change above
    • # /etc/init.d/squid3 restart
    • # /etc/init.d/pptpd restart
    • # /etc/init.d/openvpn restart
  2. adduser mynewproxyuser
    • in Case you want to create a new one
  3. adduser mynewproxyuser proxy
    • Allow „mynewproxyuser“ to use the proxy
  4. Try to connect to your proxy via Port: 3128
    • If you can auth Successfully, then you are a lucky guy
      • Check, if you can open any other site, like,,
        • OK? GOOD
        • NOK? BAD > Check Logs. And add your question to the Comments
  5. IF you can connect to your Proxie and can use the Internet, fine
  6. IF NOT
    1. Check if the Service is running
      1. ps auxwww | grep squid
      2. check logs
      3. run squid in non deamon mode for testing
        1. # squid3 -N
      4. remember to let squid on the first time of run create the Local Cache
        1. # squid3 -z

If everything got fine, you are now able to use your Server as a Proxy and a VPN-tunnel.

[EN] Howto block an IP-Adress with iptables

You want to block an IP on IPtables? or an IP-Range


then its just easier as you think:


# sudo nano /usr/local/bin/block-ip

Insert the following Code:

iptables -A INPUT -s $1 -j DROP

# sudo chmod 700 /usr/local/bin/block-ip

And your done.

you can just now use as root
# blockip
You’ll block this single IP. I aint tested it with a Subnet yet, like – but i think it might work.

[EN] Reduce the size of the Offline Folder file (.ost)

Reducing the size of the Offline Folder file (.ost) file may improve performance if you have deleted a large quantity of items. This procedure does not delete any items that are saved on the server.

  1. Delete any items that you do not want to keep, and then empty the Deleted Items folder.
  2. On the Tools menu, click Account Settings.

    The Account Settings command is missing.

    The Account Settings command is on the Tools menu in Microsoft Office Outlook 2007. If you are using an earlier version of Outlook, the following instructions do not apply. Use the Help that is included with that product. If the title bar of the program that you are using displays Microsoft Outlook Express, you are using a program that is not the same as Outlook. See Help in Outlook Express for assistance.

  3. In the list, select Microsoft Exchange Server, and then click Change.
  4. Click More Settings.
  5. Click the Advanced tab, and then click Offline Folder File Settings.
  6. Click Compact Now.


  • To delete an item from both the online and offline folders, select the item, and then press DELETE.
  • If you are using an Exchange account in Cached Exchange Mode, only the selected folder will be cleared from the local .ost file. The items on the server will be downloaded again to the .ost file on the next synchronization, if the folder is selected under Folder Options in Send/Receive Settings for the Exchange Server e-mail account.
  • When you use Cached Exchange Mode, public folders favorites are not synchronized by default. If you choose to synchronize public folders, the size of your Offline Folder file (.ost) may increase significantly.

  3. Click Compact Now.

Note:    You do not have to exit Outlook after you compact a .pst file.

[EN]Howto add on Microsoft Outlook 2007 Local Archive (*.pst (Personal Storage))

Microsoft’s Outlook email management program stores all user data, including messages, contacts, and calendar entries within a single .pst file called a Personal Folders file. As this file grows, it can start to cause errors within Outlook, including program crashes or data corruption. While backups are an important safeguard against potential data loss, they alone do not adequately circumvent these kinds of errors.

Archiving old or infrequently used data serves to reduce the overall size of the .pst file, and should be done periodically depending upon the volume of email your Outlook program handles.  Users who send and receive relatively large amounts of email or frequently deal with files containing large attachments will need to archive more regularly. Typically, Outlook’s performance will begin to be impaired as .pst file sizes exceed 500 MB.

Note: Before beginning the archive process, it is important to backup your current .pst file.  A quick backup procedure may be found in our Backing Up Personal Data Files article.

To manually archive data within Microsoft Outlook 2007, take the following steps:

1. Open the File menu, click New and select Outlook Data File.

2. Select Office Outlook Personal Folders File (.pst)  and click OK.

3. For the purposes of this demonstration, we have named the file „archive“ below. The name of the archive file may be chosen arbitrarily; however, it is important that Personal Folders File is the option that is chosen from the „Save as type:“ drop-down menu. Once the file has been named, click OK to continue.

4. You will be prompted at this point to name the newly created file. This is the simply the title that will appear in the navigation pane of Outlook once the .pst file has been successfully created.  If you would like to secure your archived data with a password you may do that within this window also.  Here, we have given our file the name „Personal Folders Archive.“ The new folder should now show up in the navigation pane as shown below.

5. You are now able to move email messages out of your main .pst file and into the newly created Archive folder.  You may use the drag-and-drop feature to move data from folder to folder or utilize the Move to Folder… option that appears when appropriate files are right clicked. Entire folders may be moved in a similar manner.

Note:  Once you have finished moving files to the archive file, it will be necessary to compact your primary .pst file. For more information, see the article „Compacting Your Personal Data File.“  This is very important, because Outlook will not automatically reduce the size of the file after you archive data; you must shrink the file manually using the Compact feature.
