Hi Aaron,

If you use the above natting then you would lose all the management access on the outside interface, you would need to do port forwarding, kindly remove the nat statements that you have and you can use this:

object service rdp_login

  service tcp destination eq 3389

nat (outside,inside) source static any any destination static interface RDP_static service rdp_login rdp_login

and the access-list is also wrong, it should be:

access-list remote_access extended permit tcp any host 172.20.1.1 eq 3389

and it would work smoothly for you.

Hope this helps.

Thanks,

Varun
