NAT, port-forwarding and external access

[leidegre]

I'm having trouble enabling some services through my VM. My current situation won't allow me do anything besides NAT and I know I've made this work before, I can't just remember how.

The problem has to do with accessing the services exposed by my VM from any external computer trying to communicate with the host.

I can't seem to make the host computer translate/forward the necessary traffic. I've tried using ipfw and forward to say that any attempt to connect to port 53557 should atually go to my VM's IP address.

I can access my VM's service through it's IP address and port number but I can't seem to just forward traffic to the host, to this VM.

I wan't localhost:53557 to map to my VM as well as any connection atempt made to the external IP map to the VM.

How would I go about setting this up?

For an example have a look at:

It's not enough. Below is ifconfig and lsof output.

sudo lsof -i -P | grep -i "listen" | grep vmnet

vmnet-nat 70 root 6u IPv4 0x6b58a68 0t0 TCP *:53557 (LISTEN)

The problem is still, localhost:53557 or any atempt to connect to my external IP:53557 on en5 fails. The only thing which current works is connecting to 172.16.109.128:53557 directly (the gues VM from the host). I need to make the same thing possible from any external computer.

I appricate any help,
