Borman Zero Millimeter LLC Wind River Systems Wind River Systems Potomac, MD Potomac, MD Mendota Heights, MN [email protected] [email protected] [email protected] Abstract The BSD/OS IPFW packet filtering system is a well engineered, flexible kernel framework for filtering (accepting, rejecting, logging, or modifying) IP packets. IPFW uses the well understood, widely available Berkeley Packet Filter (BPF) system as the basis of its packet matching abilities, and extends BPF in several straightforward areas. Since the first implementation of IPFW, the system has been enhanced several times to support additional functions, such as rate filtering, network address translation (NAT), and traffic flow monitoring. This paper examines the motivation behind IPFW and the design of the system. Comparisons with some contemporary packet filtering systems are provided. Potential future enhancements for the IPFW system are discussed. 1 Packet Filtering: An Overview might choose to copy only this data. -

Multiple Internet Connections by Balancing Traffic and Managing Failover with Zeroshell
Multiple Internet Connections by Balancing Traffic and Managing Failover With Zeroshell The purpose of this document is to describe the creation of a router to access a network that uses multiple Internet connections in order to balance the outgoing LAN demand and to obtain network access redundancy, managing fault situations for one or multiple lines. To reach our objective, we shall use the Net Balancer module by Zeroshell. Lastly, we shall examine the possibility of aggregation (Bonding) of VPN aimed at increasing the bandwidth for point-to-point connection between remote locations via the Internet. Is it really possible to increase the Internet connection bandwidth? The answer to this question is not, "yes, absolutely." It depends on what you mean by increasing the Internet connection bandwidth. In essence, the Net Balancer distributes requests originating from the LAN by round-robin (weighed) policy over multiple Internet gateways. In other words, if at a given point in time there is only one LAN user making only one TCP connection (e.g. he executes only one download from the web), his traffic will flow from a single gateway, thus it would not benefit from balanced connections. Instead, if the LAN is crowded with users, each executing multiple requests at the same time, as a whole, their connections will have access to a higher bandwidth, equal to the sum of the single-access bandwidths. We then conclude that a single connection may never have more bandwidth than what offered by a single link, while multiple simultaneous connections will, on average, altogether have access to a greater bandwidth, which will stretch to the sum of the bandwidths of all the Internet links being balanced. -

How to Configure Some Basic Firewall and VPN Scenarios
AlliedWareTM OS How To | Configure Some Basic Firewall and VPN Scenarios Introduction This document provides examples that illustrate common configurations for security routers. You may want to make changes or enhancements to these configurations to customize them to your particular requirements. However, with the configurations provided here, you can be quickly operational with a reliable and secure Internet connection. What information will you find in this document? The first section provides the basic configuration for two likely methods that will be used for an Internet connection from the security router: z "Script A: basic Ethernet connection" on page 3 z "Script B: basic PPPoE configuration" on page 7 The second section provides three extra configurations to enable the router to support three popular forms of Virtual Private Network (VPN) connection, followed by a configuration for a Mail server on a DMZ. One or more of these additional scripts can be added to either of the basic configuration scripts: z "Script C: internal L2TP Network Server (LNS)" on page 11 z "Script D: IPsec tunnel" on page 13 z "Script E: PPTP server on LAN behind router" on page 16 Then the second section ends with an example in which private IP addresses are used on the DMZ LAN: z "Script F: DMZ using private addresses" on page 17 C613-16069-00 REV B www.alliedtelesis.com Introduction > Related How To Notes These six configuration examples are as general as possible, and no actual IP addresses have been specified. IP addresses are represented by placeholder names in angled brackets, for example, <dmz-ip-address>.
