ISA Rule for Remote Desktop?

I am looking at a rule in ISA 2004 named SBS RWW Inbound Access Rule. It
has an Allow action, the protocol is named
SBS_Custom_Protocol_TCP_Outbound_4125 and in the details for that protocol
it is using port 4125 Outbound. It is from the External listener to Local
Host.

My questions: Is that rule correct for allowing Remote Desktop from outside
the LAN and should there be a rule for port 4125 Inbound as well? I'm not
seeing one.

Thanks
Jeff
