Dhudike(Moga) Dhudike (Moga) Abstract : There are two IP addresses for a typical home network: one for local devices to connect to across the local area network (LAN), another for the external or wide area network (WAN) Internet connection. A virtual private network (VPN) is a method for the extension of a private network across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus are benefiting from the functionality, security and management policies of the private network. The aim of this method of course is to balance the traffic so as to avoid the congestion. Keywords: Load balancing, IP network, VPN, NAT. (1) INTRODUCTION network and the Internet. Firewall prevents unauthorized use and access to your network. The job of a firewall is to carefully analyze data entering and exiting the network A default IP address is normally set to internal LAN, private based on your configuration. It ignores information that number for example, 192.168.1.1 for their internal IP comes from unsecured, unknown or suspicious locations. A address. No matter the brand of router, its default internal IP firewall plays an important role on any network as it address is listed in the manufacturer's documentation. This provides a protective barrier against most forms of attack IP address can be changed by Administrators during router coming from the outside world. Firewalls can perform a setup or at any time later. These private LAN-IP address variety of other functions, but are chiefly responsible for remains fixed, unless someone manually changes it. The controlling inbound and outbound communications on external WAN-IP address of the router is set when the router anything from a single machine to an entire network. connects to the Internet service provider. This address can also be viewed on the router's administrative console. IP-tables In network security, use of IP Tables is becoming very important.

Many software firewalls have user defined controls from potential Internet attacks. There are many different for setting up safe file and printer sharing and to block default configurations for these devices - some allow no unsafe applications from running on your system. communications from the outside and must be configured, Additionally, software firewalls may also incorporate using rules, others (like those available for the home market) privacy controls, web filtering and more. are already configured to block access over risky ports. Rules can be as simple as allowing port 80 traffic to flow Software firewalls, also sometimes called personal firewalls, through the firewall in both directions. are designed to run on a single computer. These are most commonly used on home or small office computers that Firewalls are also used for Network Address Translation have broadband access, which tend to be left on all the time. (NAT). This allows a network to use private IP addresses that are not routed over the Internet. Private IP address Computers communicate over many different recognized schemes allow organizations to limit the number of publicly ports, and the firewall will tend to permit these without routed IP addresses they use, reserving public addresses for prompting or alerting the user. For example, computers Web servers and other externally accessed network access Web pages over port 80 and use port 443 for secure equipment. NAT allows administrators to use one public IP Web communications. A home computer would expect to address for all of their users to access the Internet - the receive data over these ports. However, a software firewall firewall is "smart" enough to send the requests back to the would probably block any access from the Internet over port requesting workstation's internal IP. NAT also allows users 421, over which it does not expect to receive data.

  • Writing Netfilter Modules
    Writing Netfilter modules Jan Engelhardt, Nicolas Bouliane rev. July 3, 2012 The Netfilter/Xtables/iptables framework gives us the possibility to add features. To do so, we write kernel modules that register against this framework. Also, depending on the feature’s category, we write an iptables userspace module. By writing your new extension, you can match, mangle, track and give faith to a given packet or complete flows of interrelated connections. In fact, you can do almost everything you want in this world. Beware that a little error in a kernel module can crash the computer. We will explain the skeletal structures of Xtables and Netfilter modules with complete code examples and by this way, hope to make the interaction with the framework a little easier to understand. We assume you already know a bit about iptables and that you do have C programming skills.

ONDREJ LICHTNER AUTHOR VEDOUCÍ PRÁCE Ing. ONDŘEJ RYŠAVÝ, Ph.D. SUPERVISOR BRNO 2014 Abstrakt Cílem diplomové práce je návrh síťové konfigurační knihovny s dùrazem kladeným na pøenositelnost mezi operačními systémy na bázi Linuxu a BSD a roz¹iøitelnosti podpory knihovny. V druhé kapitole práce zkoumá dostupné konfigurační rozhraní obou operačních sys- témù. Detailně pak rozebírá vlastnosti rozhraní Netlink socketù, které je primárním konfig- uračním rozhraním pro síťové prvky na Linuxu, a systémové volání ioctl, které má na Lin- uxu menší schopnosti, ale zato je primárně používané na BSD a jiných UNIX systémech. Jsou též zkoumané rozhraní pro konfiguraci rozdílných firewallù. V třetí kapitole je práce zameøená na konkrétní typy síťových zařízení, specifika je- jich konfigurace a jejich návaznost na rozhraní jádra popsané v druhé kapitole. V ètvrté kapitole jsou formulovány požadavky na konfigurační knihovnu: jednoduchá roz¹iøitelnost, pøenositelnost na rùzné operaèní systémy, podpora sledování změn a událostí a roz¹iøitelnost o rùzné typy uživatelských rozhraní. Na základě výzkumu z pøedcházejících dvou kapitol je pøednesen návrh knihovny. Návrh definuje konfigurační rozhraní jako hierarchii abstrak- tních tříd, oddělených od implementace. To umožnuje mít současně několik implementací stejného konfiguračního rozhraní i v rámci jednoho operačního systému. Jako vstupní rozhraní knihovny je definovaná třída LibNCFG, která má na starosti tyto konfigurační objekty vytvoøit namísto uživatele.
