Hi Ahmed,

run a span session and wireshark so you can analyse which traffic is reaching R1 and wich destination they have.

For the rest it is quite hard to advice you because not so many info.

Please clarify what you mean when you say " i cannot ping them from the Internet" so to help if possible

Hi Ahmed,

I hope you could have done PAT for the internal users to connect to the internet. So you cannot ping them from the internet. If you do a one to one NAT then you will be able to ping the connected user/pc from internet.

Please do rate if the given information helps.
