What is wrong with this network, why am I unable to connect to the internet from the network 172.16.1.0 here?



I've done all the routing setup using GUI (that should not cause the problem, though). Any help appreciated!

  • Hello cdummie and welcome to NE ... it's much better to copy/paste the output of commands (eg show ip route) rather than images ... means they get indexed and so on. In your question, what are the routes on R3? It's also most helpful if you copy/paste the (no passwords please!) configurations.

R2's default route points back to R1. Instead it needs to point to R3 via Serial0/0/1.

How to calibrate 16:9 built-in touch-screen to a 4:3 resolution?

Image
up vote 0 down vote favorite I need help with an issue we're facing in a project where we are moving from a Windows-based POS environment to one running on CentOS7. The problem consists of a number of factors, please find the details below: The supplier of our POS application will only deliver an application that is hard-coded to run in a 1024:768 4:3 format. The hardware we are using is a POS unit from HP that has a built-in 16:9 touch-screen. The employees using this solution is not supposed to see nor have access to anything but the POS application.

Image
1 1 I've setup a wireless network using a Linksys-Router (DD-WRT) as an AP and a TP-Link repeater for range extension. To manage bandwith for specific users, I've setup QoS-Rules on the AP (DD-WRT) using MAC-Priority: However the AP shows only the Repeater's MAC and the MACs of users inside the AP-Range. The MAC addresses of users behind the Repeater are not listed : The purple MAC is not listed in the AP-Clientlist. Its related to a device connected via the TP-Link repeater. Q: How can I setup MAC-Priority for repeater-clients? Do I simply add the purple MAC in AP-MAC priority list although it's not listed as a client? I want to setup specific priority instead of giving one priority for all clients behind the repeater by adding the repeater's MAC in the MAC priority list in the AP as ...
