Broadcast messages can be sent by any IPv4 host. As you say PCs use broadcast messages, Switches flood broadcasts out of every port apart from the port the broadcast came in on, but technically any IPv4 device has the ability to use broadcast traffic for network communication. take a Network printer for example that is set up to obtain a DHCP assigned ...

There's many... you didn't specify much so i'll give my recommendation. I love GNS3: https://www.gns3.com/ Works best in linux. Then you can see: http://www.unetlab.com/ http://virl.cisco.com/ I have not tested the ones below.

Dropping the [RST,ACK] and [FIN,ACK] will not work. There are many application like ftp upload that will simply fail to ack the completion of the FTP transfer. The comments by gscott are the correct method, but one additional requirement is needed. You must make them strict by applying the policy iptables -P OUTPUT DROP iptables -P FORWARD DROP iptables -...

No, you can't The WAN port on that device is a routed port. It can have a different network address than your LAN network address and the LAN traffic would be routed through the WAN port to get to your ISP. Unfortunately there are no Layer 3 ports on your switch side of the router. You asked. Is there any way I can configure one of the LAN port out ...

Most people's Internet bandwidth is downstream. Your own router does not make the packet scheduling decisions for downstream traffic, it is the ISP's routers that do that. They will almost certainly have some form of QoS scheduling even if it's as basic as WRED. Without any scheduling, a router will operate FIFO (first in, first out) with tail drop. That ...

Quality of Service doesn't evenly distribute services based on the number of clients requesting the data, rather, it rations the bandwidth based on the services being requested. Example; one user is requesting Netflix, the other is just surfing web pages. If streaming video is higher on the list of priorities than HTML, then the first user's data will be ...

Port forwarding and DMZ are related to sessions initiated on the WAN side and redirected as configured to the proper local machine. For that reason, unless you have advanced configuration or shell access to your router (which does not appear to be your case), it is not possible to define the rules needed in it. Even if you could, it would cause a conflict ...

Have you tried looking your user manuals, I think that might be able to help you. There you can get your answers in Appendix A. Here is the link for your manual. if it works say it in comment. https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&sqi=2&ved=0ahUKEwiI-s_lkaTNAhVLo48KHZlDC7gQFggbMAA&url=http%3A%2F%...

Assuming that when you say "The network setup is not working though" you mean that those hosts are no longer being provided a reserved IP address via DHCP... According to various sources, the ARP Binding feature of TP-Link routers isn't for assigning DHCP reservations. You'd need to either find the DHCP reservation feature on the TP-Link and add the ...

NAT reflection is disabled by default, so tests from your internal network are going to fail. From pfSense's Troubleshooting Guide: Port forwards do not work internally unless NAT reflection has been enabled. Always test port forwards from outside the network, such as from a system in another location, or from a 3G/4G device. I think I've tripped over ...

In addition to everything else Per has said. You're AP gateway is pointed at itself. It needs to be pointed at the router.

You need to disable the DHCP server on the TP-link box. Most likely your wireless clients are getting DHCP off your AP and you haven't configured a correct gateway and DNS.

not sure exactly what the problem was but reassigning a new range of ip addresses (no longer using boring 192.168.. ..) and rebooting my board without lan connected did the trick

It should be possible to do this by simply not connecting your router to the internet.

Piping the syslog message to netcat will add the hostname. A simple way is to pipe messages using netcat (nc) in the syslog.conf file as follow: *.* "TAB" | nc RemoteLogServer -u 514 -w 1" A TAB character must be inserted before the pipe symbol.

I got help from Spiceworks community and fixed this issue. It is because the previous firmware were not stable. The issue was resolved after I updated it to the latest firmware. If you are interested, you may refer to the post here.

What you are trying to do won't work. By plugging in the AP to the modem, the modem is going to assign the public IP you are allocated to the AP. When you connected to the AP, you won't even get a DHCP address because that is handled by your router. If your router has better wireless range. Just unhook the AP. What is the point of having an AP if it has ...
