port forwarding to linux virtual machine

I am trying to run an experimental server using port 3838 on CentOS in a Parallels virtual machine. The idea is to have requests coming to the host IP on port 3838 be forwarded to the virtual machine's IP address on port 3838. I have tried adding the following the rule to the port forwarding rule under

Parallels Preferences -> Advanced -> Network Change Settings

port on mac port type virtual machine's IP address destination port
3838 TCP 10.211.54.4 3838

However, this is not working. I can still reach the host IP on port 80, which I want to keep in tact, so at least I haven't broken anything I want to keep. Am I barking up the wrong tree here?

Thanks.

1. under parallels "preferences" I advanced, I checked "enable IPv4 DHCP, Start address 10.211.55.20, end address: 10.211.55.254, and subnet mask 255.255.255.0

2. added port forwarding rule as 388, TCP, 10.211.55.2

3. ran the "setup" too -> networkd config -> device config, for eth0 l used static IP as 10.211.55.2, netmask of 255.255.255.0 and gateway IP of 10.255.55.20

running ifconfig gives:

I can connect to the server from within centos if I type into firefox 10.211.55.2:3838, but I can not reach the server from outside cnetos.

Thanks agian for any suggestions.
