Hello everyone,
My tunnel has been successfully established, but when I traceroute from side A to B, the request goes outside the tunnel, I have tried too many different configuration but I give up, so before I go completely crazy, I am asking if anyone could help me.
I think is important to let you know, I have no strong skills in routing.
The scenarium is:
1) SIDE A - 177.7.10.20 With no subnet – is only a single server
2) SIDE B - 201.7.16.24 Subnet – 192.168.0.0/24
The following posting, refers the status on side A. If necessary let me know if I need to post the same of side B
