Ping a valid device IP with in this case Remote Desktop enabled (TCP:3389)

SA inducate that the port is open.

Status > Ping/Trace
This page lets you test connectivity using Ping or Traceroute, or by sending a TCP or UDP packet to a specific port.

••

Target Address can be an IP address or a DNS host name, provided that DNS resolution is correctly configured(System > DNS).
Source Address can be any (blank), or the IP address of a specific interface.

TCP specific note:•••

No response means that either there is no host at the specified address, or that a firewall may have blocked
the packet.
A response with flags=RA means that the port is closed.
A response with flags=SA means that the port is open and the server accepted the request.

UDP specific note:••

No response may or may not indicate a problem; even when the port is reachable and open, the target host isunlikely to respond to a packet that most likely doesn't contain any valid protocol data.
An "ICMP Port Unreachable" response means that the target host is reachable, but the port is closed (otherICMP messages may also be received, e.g. from routers on the path).

Note: You will only be able to ping or traceroute through a VPN tunnel if the source address is within the "Local Network" subnet as configured for that particular tunnel.
