4/30/2024 0 Comments Ping with loopback plug![]() In this case, a loopback cable wouldn't work properly, would it? The loopback would send the ping, but it couldn't send the reply? If that's the case, could software be written to reply?Īlso, I've tried using the Microsoft Loopback adapter and capturing the packets, but it doesn't actually show anything. It seems that the network test is just pinging the destination address like crazy (I had my duty cycle up to 99%) and waits for the reply. Placed that IP in the destination of the network settings (all available ethernet ports) On number 1, is that due to the internal loopback not going through all of the layers (physical, link, network, etc.)? The best way to test Ethernet is by pinging a router you've connected on the network. The internal loopback doesn't test much of the hardwareĢ. I've searched on these forums for Ethernet loopback and you guys seem to reiterate these two things:ġ. Once I get this figured out I will be able to use the same concept for other clients.I'm working with the network test right now (networking has never been a strong suit). I believe in Mikrotik and I want to stay with this router. I used port map and netmap feature of the RouterOS. Do you have another idea to make this work? Also I have a number of port forwarded ports that they are currently using. I was going to use iBGP to notify the upstream that the DSL is the route to use for incoming request to the 54.1 network. Below, Ill highlight a less common implementation of performing NAT on an internal loopback in a different zone, to highlight some requirements: In this example, the loopback interface is set to private IP 10.2.2. I used static default routes with the cost being higher on the DSL. The only way to have the 54.1/28 available was to add a bridge and add the 54.1 as its address. On 192.168.1.36 I can ping the loopback and the source machine. ![]() My goal was that I would have routes to or from the 54.1 for primary and backup. ![]() So I set up the 750G with port 1 as the wireless and port 2 as the DSL, added a bridge with an IP subnet of 54.1 and port 3 has the 10.10.10.0/24 network. I sold them 3 Mbps wireless internet connectivity and they wanted to keep the DSL as a backup. The need more upload bandwidth than is available via DSL. Currently they are using a /29 which is also NAT'd to the 10.10.10.x/24. They want to have the 54.1 network available to the internet since they have various servers which they host. I get timeouts on my laptop until I plug the wireless cable back in. The ping goes out port 1 and if I disconnect the cable to port 1 (simulating a wireless outage) the dsl port does not pick up and continue. ![]() I started a ping on my laptop which is connected to the port 3 or the 750G which has an IP address of 10.10.10.220. The ping command will send 4 by default if -n isnt used.
