Difference between RDP, ICMP and IP protocols.

I have set up an IPSec policy for a machine to allow RDP and ICMP but require security for all IP traffic.
Now I can ping the machine to which the policy is applied but can not RDP to it.
I was wondering why ICMP is working and RDP is not, though RDP works at the transport layer and the ICMP at the IP layer or network layer.

Have you allowed the port TCP 3389 which is used for RDP?

Oh yes, I created a rule that allows RDP for TCP port 3389, but it seems like the Require security for AllIPTraffic overrides that rule. But I wonder why it doesn't override the rule of ALLICMPTraffic(permit).

I gues I should have put 3389 where it says "From this port" , and select to Any Port.
What I did was "From Any Port" to "This Port" and typed 3389 in This port field.

Now it works.
