Access-group In/out. Hi Friends, I'm confused on the Ip access-group in interface command Vs IP access-group out command.

Access-group In/out

How will it affect the access-list which is currently configured with Ip access-group in interface subcommand and if we change it to ip access-group out interface subcommand. Per my understanding, it will change the direction in which the access-list logic is applied. Please see below the example: Between GRE/IPSEC and IPSEC VPN tunnels Cisco Forum FAQ. Suggested prerequisite reading»Cisco Forum FAQ »Setting Up Private Site-To-Site Connections Introduction IPSec VPN tunnel is one way of setting up private site-to-site connection by utilizing public network (the Internet).

Since it is utilizing public network, there would be no need to have dedicated physical circuit to interconnect the sites, hence requiring low cost to setup while maintain private and secure connection. Untitled. More Restrictive Subnet Masks. Previous Next Additional bits can be added to the default subnet mask for a given Class to further subnet, or break down, a network.

More Restrictive Subnet Masks

When a bitwise logical AND operation is performed between the subnet mask and IP address, the result defines the Subnet Address (also called the Network Address or Network Number). There are some restrictions on the subnet address. Node addresses of all "0"s and all "1"s are reserved for specifying the local network (when a host does not know its network address) and all hosts on the network (broadcast address), respectively. To calculate the number of subnets or nodes, use the formula (2n-2) where n = number of bits in either field, and 2n represents 2 raised to the nth power.

The best way to do this is to practice your skills over and over again across many labs. Unfortunately, without a way to document your labs, a lot of what you practiced is still forgotten. NetBrain Personal Edition can help you document your labs automatically, by allowing you to: Discover devices and create rich diagrams from your configuration data Automatically capture, organize, and annotate show command results Take notes alongside the map with the built-in Notes tab Once your lab is fully documented inside a NetBrain Qmap, you can review it down the road without the hassle of having to rebuild it.

Personal Edition Highlights. 911networks.com - Cisco - How BGP attributes are applied. Access Control Lists and IP Fragments. Introduction This White Paper explains the different kinds of Access Control List (ACL) entries and what happens when different kinds of packets encounter these various entries. ACLs are used to block IP packets from being forwarded by a router. covers security considerations for IP fragment filtering and highlights two attacks on hosts that involve IP fragments of TCP packets, the Tiny Fragment Attack and the Overlapping Fragment Attack. Blocking these attacks is desirable because they can compromise a host, or tie up all of its internal resources. also describes two methods of defending against these attacks, the direct and the indirect.

Regular readers no doubt have noticed that I haven't posted anything new in the past few months. I've been pretty busy with the holidays, home projects, and adjusting to a new job, and haven't had much time or motivation to devote to writing.

Good news though: I have started on a long-overdue refresh of the Packet Life design and code base. When I originally debuted Packet Life, I ultimately wanted it to serve as major community hub, so I built in features like the wiki and discussion forum. Although Packet Life has grown quite popular over the last few years, these areas of the site have seen little activity. Acknowledging that there are more active and useful sites out there which serve these functions, I've decided to chop off some of the bloat in favor of focusing on the blog and the site's other more popular features.
