Ipv4 WAN (Internet) Layer 2 Tunneling Protocol (L2TP) Configuration on RV120W and RV220W
IPv4 WAN (Internet) Layer 2 Tunneling Protocol (L2TP) Configuration on RV120W and RV220W Objectives Layer 2 Tunneling Protocol (L2TP) establishes a Virtual Private Network (VPN) that allows remote hosts to connect to one another through a secure tunnel. It does not provide any encryption or confidentiality by itself but relies on an encryption protocol that it passes within the tunnel to provide privacy. One of its biggest advantages is that it encrypts the authentication process which makes it more difficult for someone to "listen in" on your transmission to intercept and crack the data. L2TP does not only provide confidentiality but also data integrity. Data integrity is protection against modification of date between the time it left the sender and the time it reached the recipient. This document explains how to configure the IPv4 WAN (Internet) for use with Layer 2 Tunneling Protocol (L2TP) on the RV120W and RV220W. Applicable Devices • RV120W • RV220W Software Version • v1.0.4.17 IPv4 WAN (Internet) L2TP Configuration Step 1. Log in to the web configuration utility and choose Networking > WAN (Internet) > IPv4 WAN(Internet). The IPv4 WAN (Internet) page opens: Step 2. Choose L2TP from the Internet Connection Type drop-down list. Step 3. Enter the username provided from ISP in the User Name field. Step 4. Enter the password provided from ISP in the password field. Step 5. (Optional) Enter the secret pass phrase if provided by the ISP in the Secret field. Step 6. Click the desired radio button for the Connection Type: • Keep Connected — This keeps the device connected to the network for all the time. -

GPRS Tunneling Protocol (GTP) Processing
TECHNOLOGY BRIEF GPRS Tunneling Protocol (GTP) Processing GPRS Tunneling Protocol or GTP for short is a mechanism used exclusively in cellular SUMMARY networks to tunnel IP packets through a mobile network core. The protocol was Comprehensive discussion of GTP introduced in the late 1990s when the first generation of packetized data—known protocol and how an Accolade as General Packet Radio Services or GPRS—was adopted. GPRS is often referred to adapter can help with GTP as 2.5G because it runs over GSM (2nd Generation or 2G mobile technology). GTP deduplication has moved on from those humble beginnings and is used in an updated form in KEY POINTS both 4G (LTE) and emerging 5G cellular networks. The main benefit of GTP is that • GTP is used exclusively in mobile a user’s IP address can be decoupled from routing and related decisions within networks a mobile network core. This is what allows a cellular customer to move around • Accolade ANIC adapters can fully from base station to base station and still maintain uninterrupted connectivity parse GTP packets and offer to external networks such as the Internet. It also allows for multiple services such value added capabilities such as as VoLTE (Voice over LTE) to be provisioned on the same device. In short, GTP is a deduplication crucial tunneling protocol that is indispenable in all modern mobile networks. HOW IT WORKS Figure 1 depicts a mobile phone (referred to as “user equipment” or “UE” in the industry) accessing an Internet web server with IP address 74.125.71.104. The phone or UE is initially connected to base station #1 (referred to as an eNodeB or “eNB” in LTE) and generates a simple IP packet to access the web server. -

Ipv6 Security: Myths & Legends
IPv6 security: myths & legends Paul Ebersman – [email protected] 21 Apr 2015 NANOG on the Road – Boston So many new security issues with IPv6! Or are there… IPv6 Security issues • Same problem, different name • A few myths & misconceptions • Actual new issues • FUD (Fear Uncertainty & Doubt) Round up the usual suspects! Remember these? • ARP cache poisoning • P2p ping pong attacks • Rogue DHCP ARP cache poisoning • Bad guy broadcasts fake ARP • Hosts on subnet put bad entry in ARP Cache • Result: MiM or DOS Ping pong attack • P2P link with subnet > /31 • Bad buy sends packet for addr in subnet but not one of two routers • Result: Link clogs with routers sending packet back and forth Rogue DHCP • Client broadcasts DHCP request • Bad guy sends DHCP offer w/his “bad” router as default GW • Client now sends all traffic to bad GW • Result: MiM or DOS Look similar? • Neighbor cache corruption • P2p ping pong attacks • Rogue DHCP + rogue RA Solutions? • Lock down local wire • /127s for p2p links (RFC 6164) • RA Guard (RFC 6105) And now for something completely different! So what is new? • Extension header chains • Packet/Header fragmentation • Predictable fragment headers • Atomic fragments The IPv4 Packet 14 The IPv6 Packet 15 Fragmentation • Minimum 1280 bytes • Only source host can fragment • Destination must get all fragments • What happens if someone plays with fragments? IPv6 Extension Header Chains • No limit on length • Deep packet inspection bogs down • Confuses stateless firewalls • Fragments a problem • draft-ietf-6man-oversized-header-chain-09 -

Virtual private networks (VPNs), PPTP, L2TP, IPSec, tunneling, encryption, SSL, QoS Abstract. Virtual private networks (VPNs) are becoming more and more important for all kinds of businesses with a wide spectrum of applications and configurations. This paper presents the basic concepts related to VPNs. These include the different types of VPN services, namely Intranet, Extranet and Remote Access VPNs. The concept of tunneling, which is fundamental in VPNs, is discussed in great detail. The tunneling protocols that are employed by VPNs, such as PPTP, L2TP and IPSec are also presented. Furthermore, the issue of Quality of Service, QoS, support in VPN configurations is briefly addressed. 1 Introduction The best way to come up with a definition of the term Virtual Private Network (VPN) is to analyze each word separately. Having done that, Ferguson and Huston (1998) came up with the following definition: A VPN is a communications environment in which access is controlled to permit peer connections only within a defined community of interest, and is constructed through some form of partitioning of a common underlying communications medium, where this underlying communications medium provides services to the network on a non-exclusive basis. Ferguson and Huston also provided a simpler and less formal description. -
