Accessing VM box behind the MT router

I would like to thank everyone in advance for any assistance. As you can see this is my first MT product and first post. I am trying to set up the Router board to allow me to access a couple of servers that have public IP that are inside my network. Specifically the VM server. I have tried to follow some utube video and set up 4 NAT rules that I think should work but are clearly not. When the NAT rules are active I am not able to log into the MT externally only from the internal 10.x.x.x network. I am however able to ping the VM server but not log into it. When the 1st NAT rule is shut off then I can get into the MT externally but the ping no longer working. I would love some advice on what I am doing wrong. The 4 rules I have listed below. As a run down on the setup I have a public IP provided by my ISP and a /28 range for the internal public IP also provided by my ISP.

Rule 1 under the general tab the chain is dstnat and the DST address is my public IP of the router, Action tab has action dst-nat and the to address is the /28 range from my ISP
Rule 2 under the general tab the chain is srcnat and the SRC address is the /28 range from the ISP, Action tab has action src-nat and the to address is the public IP
Rule 3 under the general tab the chain is dstnat and the DST address is the /28 range from the ISP, Action tab has action dst-nat and the to address is the public IP
Rule 4 under the general tab the chain is srcnat and the SRC address is the public IP of the router, Action tab has action src-nat and the /28 address range.

Basically what I want the router to do is just act as a bridge from any traffic to and from the range of public IP that I have inside my network.

Thanks again for any assistance!!!
