How to enable GRE protocol?
Hi everyone I´m trying to make a vpn with pptp on CHR Mikrotik I already set the clients and all the configuration on winbox, but when I try to connect the clientes with the server it gives me a GRE error telling me that the server is blocking the comunication because the GRE its not available so I think that the protocol its not set on the DigitalOceans firewalls rules or I dont know. So it will be great if some one could help me with this. Thank you.
