Hello everyone,
I would like to ask for help with this case in PT. I have my server on a local address (first picture) and I would like to use him as an FTP server (the service is ON). I have this server behind NAT on Admin_R and there I have a port translation for logging and FTP (21 a 20). Firstly when I did this configuration it worked but after a day I opened PT again and it is not working anymore.
When I look in the letter for the communication between any L3 switch and that Server it establishes the connection, sends the username and password and it is ready for receiving the data but here happens the problem, that in the letter on Layer 4 it says that this connection does not exist.
Thank you in advance for each answer.
Have a nice day.
