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.

Is it possible to collect Nectar points via Trainline?

Image
2 Since I am not eligible for any Railcard, the only available discount/bonus scheme is Nectar Card for me. GWR, SWR, LNER and Virgin Trains allow to collect Nectar points and I have already linked a card to my GWR account. A friend suggested me to use Trainline App, because it can search for bus tickets either. I had a look at the application, but could not see any option for Nectar. Is there a way to collect Nectar points when I buy tickets via Trainline? uk trains loyalty-programs trainline share | improve this question asked Dec 2 '18 at 15:50 ahmedus 3,224 5 19 49
