Cisco ASA Static NAT Configuration

Hello

nat (outside,inside_1) source static any any destination static interface inside-server service RDP-33320 RDP-3389 no-proxy-arp

Can you please explain this NAT rule?

I have already ask you guys below question in different forum. I don’t know where. It works through above NAT rule only.

We are configuring new ASA 5506 and this is our topology.
we are having some serious issue to access remote desktop from outside.

nat (any,outside) source dynamic any-inside-networks interface description Allow Inside to Ouside

we use above rule to allow internet from inside to outside and it works and It is at number 1 in NAT rules.

Now we have few server that we would like to access from outside so we were trying to open ports.
we create network object NAT rules and access-lists for that for some reason it didn’t work so we create manual NAT before network object NAT rules. It only works when It is at number 1. That’s fine but than our internet stops working.

So we don’t have any idea what we are doing wrong.

If some can help me ASAP because we are planning to deploy ASAP
