yes router forward traffic to all ports.
Only external traffic that is destined for specific internal ports is permitted. All other traffic is denied.
Router(config)# line vty 0 4
A router is a device that routes all traffic to and from your network. A router functions by forwarding packets of data between computer networks.
which of the following will a router configure for PAT process if the traffic type is addressed for the PAT border router itself ? A. DHCP B. SNMP C. PING D. ALL OF THE ABOVE
It does not matter if you are connected through wireless or cable, your router can provide firewall protection for all of its ports on the LAN side. If your question is: Is my wireless router's firewall protecting me, although I do use it for wireless connectivity, the answer is yes. Your routers firewall protects you whether you use the wireless option or not.
A management port is typically a port which does not forward normal network traffic and is only used for remote management. It allows you telnet or SSH into the router for management purposes. Typically all other protocols are blocked on this interface and it is normally placed on the management network and is separated from all other networks passing through the router.
Generally traffic exiting a LAN is controlled at the router or firewall by setting rules in the configuration files for the router or firewall restricting what IP addresses traffic can be sent to, what devices outbound traffic can be sent from. You can also set rules controlling what outbound ports, protocols, and services will be blocked or allowed. Generally the best way to configure is "deny all and allow by exception" where all traffic is blocked by default and then rules are inserted to allow exceptions for specific traffic. You would also insert settings into the Access Control List.
In modular router the interfaces are not fixed so that we will be able to installed cards latter on this router. But in case of non modular router the interfaces r fixed, we cannot able to add ports/interfaces latter on. That's all
You have to use port forwarding.By "hosting" you mean probably running a web server. A www (http) server listens to incoming connections on a TCP port number 80. Therefore you must configure on your router a port forward, which will open port 80 on the router and forward all traffic to port 80 on your "hosting" computer. It will act as sort of an "extension", a peephole through which the world will see this specific service on your computer, which is otherwise hidden behind a "fence" (router).This is done by specifying:- which machine's port is to be forwarded (computer's IP address on the LAN)- which port on that machine will be forwarded- on which port of the router it will be forwarded- what type of protocol will be used (TCP, UDP or both). Sometimes a router won't allow both, then the forwarding must be done twice, once for TCP and second time for UDP. For a webserver TCP is enough.If you want to serve other services, like FTP or whatever, you must forward the ports used by this service. For example, for FTP it will be ports 20 & 21, for SSH - 22, for ECHO (ping response) - port 8, for secure http - port 443 etc.Search the internet for a "list of known TCP/IP ports" to find out more.
Since a router does not forward broadcast messages it automatically splits up the broadcast domains for all clients connected to them.
A hub (or L2 switch) performs data bridging/switching/forwarding at the OSI Layer 2 level for data destined to another address on the same subnet. For data to be forwarded to another subnet, that data must be routed at the OSI Layer 3 level which is performed by a Router (or L3 Switch). Routers collect various information about other networks it can forward traffic to and from, what routing protocols are used and which path(s) to forward that data to.
You can use a standard wireless router that contains 4 ports to connect 4 computers via wire, and the rest wirelessly. Or, you can connect all of them wirelessly. If you must connect all of them by wire, you can use a 16 port router. Most routers have either 4, 8, or 16 ports.
