VirtualBox Port Forwarding

Hello i have ran virtualbox on my Debian Lenny NetInstall server. Guest OS is same Debian Lenny Netinstall, i have success setup port forwarding to guest box, my xml file look like this:
Code: Select all
<ExtraDataItem name="VBoxInternal/Devices/pcnet/0/LUN#0/Config/SSH/Protocol" value="TCP"/>
<ExtraDataItem name="VBoxInternal/Devices/pcnet/0/LUN#0/Config/SSH/GuestPort" value="22"/>
<ExtraDataItem name="VBoxInternal/Devices/pcnet/0/LUN#0/Config/SSH/HostPort" value="10022"/>
so i can ssh to my virtualbox with external ip address and 10022 port of the realbox, but this only works when i'm not at home. If i try ssh to virtualbox when im in same LAN which is virtualbox i receive "Server Unexpectedly closed network Connection" this without loggin promt. (this with external ip of the realbox)
When i try to do same with internal ip address of the realbox and port 10022 i receive: Timed Out

The VM must run first, but I think you are already running it. Next, if you use the Host to connect to the machine, point the SSH client to localhost instead. There is no reason why it would block connections when you connect from a different machine on the network to the IP of the Host.

I'm using NAT, and the local ip of the virtual box is 192.168.0.2, when i try ssh to hit from real box (192.168.0.1) i get:
Code: Select all
root@debian:~# ssh 192.168.0.2 -p 10022
ssh: connect to host 192.168.0.2 port 10022: No route to host
root@debian:~#

What, you gave the VM a different IP than DHCP? Why did you do that? It should stay on DHCP, else forwarding won't work.

I received ip address from DHCP server from the real box, and i have setup fixed ip address on the virtual box to DHCP server config. Then DHCP server aways give fixed address: 192.168.0.2 to my virtual box.
I have internet connection but local lan not work on me.

Please note all the VM settings and the IP addresses of the whole network that you have.
