Allow Split Tunneling for VPN Clients on the ASA Configuration Example
ASA/PIX: Allow Split Tunneling for VPN Clients on the ASA Configuration Example Contents Introduction Prerequisites Requirements Components Used Network Diagram Related Products Conventions Background Information Configure Split Tunneling on the ASA Configure the ASA 7.x with Adaptive Security Device Manager (ASDM) 5.x Configure the ASA 8.x with Adaptive Security Device Manager (ASDM) 6.x Configure the ASA 7.x and later via CLI Configure PIX 6.x through the CLI Verify Connect with the VPN Client View the VPN Client Log Test Local LAN Access with Ping Troubleshoot Limitation with Number of Entries in a Split Tunnel ACL Related Information Introduction This document provides step-by-step instructions on how to allow VPN Clients access to the Internet while they are tunneled into a Cisco Adaptive Security Appliance (ASA) 5500 Series Security Appliance. This configuration allows VPN Clients secure access to corporate resources via IPsec while giving unsecured access to the Internet. Note: Full tunneling is considered the most secure configuration because it does not enable simultaneous device access to both the Internet and the corporate LAN. A compromise between full tunneling and split tunneling allows VPN Clients local LAN access only. Refer to PIX/ASA 7.x: Allow Local LAN Access for VPN Clients Configuration Example for more information. Prerequisites Requirements This document assumes that a working remote access VPN configuration already exists on the ASA. Refer to PIX/ASA 7.x as a Remote VPN Server using ASDM Configuration Example if one is not already configured. Components Used The information in this document is based on these software and hardware versions: ● Cisco ASA 5500 Series Security Appliance Software version 7.x and later ● Cisco Systems VPN Client version 4.0.5 Note: This document also contains the PIX 6.x CLI configuration that is compatible for the Cisco VPN client 3.x. -

How Cisco IT Uses Firewalls to Protect Cisco Internet Access Locations
Cisco IT Case Study PIX Firewall in Enterprise Network How Cisco IT Uses Firewalls to Protect Cisco Internet Access Locations Cisco PIX Security Appliance provides stateful firewall protection at smaller Internet gateways. Cisco IT Case Study / Security and VPN / PIX Firewall in Enterprise Network: This case study describes how Cisco Systems uses Cisco PIX security appliances to protect its network assets from unauthorized access. The Cisco global network is a leading-edge enterprise environment that is one of the largest and most complex in the world. Cisco customers can draw on Cisco IT's real-world experience in this area to help support similar enterprise needs. CHALLENGE “With its stateful-inspection capability, the Cisco PIX 525 Cisco Systems® gives a high priority to protecting its data and Security Appliance minimizes the IT network from unauthorized users, both outside and inside the burden by reducing the number of company. The accepted solution for many years has been to deploy a firewall in each of its multipeered Internet gateways entries in the ACLs for incoming and worldwide.

NAME DESCRIPTION Manpag.Es Fedora 31
fedora 31 manpag.es XINETD.CONF(5) XINETD.CONF(5) NAME xinetd.conf − Extended Internet Services Daemon configuration file DESCRIPTION xinetd.conf is the configuration file that determines the services provided by xinetd.Any line whose first non-white-space character is a ’#’ is considered a comment line. Empty lines are ignored. The file contains entries of the form: service <service_name> { <attribute> <assign_op> <value> <value> ... ... } The assignment operator, assign_op, can be one of ’=’, ’+=’, ’-=’. The majority of attributes support only the simple assignment operator, ’=’. Attributes whose value is a set of values support all assign- ment operators. Forsuch attributes, ’+=’ means adding a value to the set and ’-=’ means removing a value from the set. Alist of these attributes will be givenafter all the attributes are described. Each entry defines a service identified by the service_name.The following is a list of available attributes: id This attribute is used to uniquely identify a service. This is useful because there exist services that can use different protocols and need to be described with differ- ent entries in the configuration file. By default, the service id is the same as the service name. type Anycombination of the following values may be used: RPC if this is an RPC service INTERNAL if this is a service provided by xinetd. TCPMUX/TCPMUXPLUS if this is a service that will be started according to the RFC 1078 protocol on the TCPMUX well-known port. See the section describing TCPMUX services below. UNLISTED if this is a service not listed in a standard system file (like /etc/rpc for RPC services, or /etc/services for non-RPC services). -
Cisco PIX Firewall Series
Cisco PIX Firewall Series Product Overview The Cisco PIX Firewall series delivers strong security in an easy-to-install, integrated hardware/software firewall appliance that offers outstanding performance. Cisco’s world-leading PIX Firewall family spans the entire user application spectrum, from cost-conscious desktop firewalls for remote offices to carrier-class gigabit firewalls for the most demanding enterprise and service provider environments. Cisco PIX Firewalls deliver superior performance of up to 500,000 simultaneous connections and nearly 1.7 Gigabits per second (Gbps) aggregate throughput—while providing Cisco customers world-class security, reliability and customer service. Key Features and Benefits • Security — Cisco PIX Firewalls are purpose-built firewall appliances that utilize a proprietary, hardened operating system which eliminates security risks associated with general purpose operating systems. PIX firewalls also provide the latest in security technology ranging from stateful inspection firewalling, IPsec and L2TP/PPTP-based VPNs, content filtering capabilities, and integrated intrusion detection to help secure your network environment from next-generation attacks. At the heart of the PIX Firewall family is the adaptive security algorithm (ASA), which maintains the secure perimeters between the networks controlled by the firewall. The stateful, connection-oriented ASA design creates session flows based on source and destination addresses, TCP sequence numbers (which are non-predictable), port numbers, and additional TCP flags. All inbound and outbound traffic is controlled by applying security policies to each connection table entry. • Performance — Cisco PIX firewall’s highly scalable, yet very secure architecture based upon stateful inspection technology and application-aware "fixups" provides state-of-the-art performance and robust security. -
