Allowing 3389 port in ASA firewall

[sundarajay16]

Hi Folks,

Should I allow both the TCP and UDP port 3389 in the Cisco ASA 5545 firewall in order to allow RDP for accessing our terminal server from external networks.

Hi Sundar,

It is better to allow both TCP and UDP port 3389 for RDP connection.

Perhaps it should be mentioned that UDP-transport is only relevant with W2012 and higher. Older versions only used TCP as transport.
