Hello there,

I have a host on ubuntu and i think i would like to virtualize my web-server. So, to be more clear i have for instance the ip 92.124.74.8 to the main server (where virtualbox will be installed)

After i will install the web-server into virtualbox it will have the address 196.168.1.10

So, how can i specify on the main server 92.124.74.8 that all the requests on port 80 to be transfered on 196.168.1.10 (virtual machine). The problem is that on 92.124.74.8 i don't have access to the router/switch.

Is there a possibility to make this forward from the main machine 92.124.74.8 ?

Thank you a lot.

Hi there,

As I can understand you want http machine requested by the clients to be forwarded to guest machine by the host machine. Can you let us know as to which type of ethernet configuration you are using for guest machine whether NAT or Bridge?

Also it would be good to know which VM solution you are using (Virtual Box or VMware)?

You can forward the http request by enabling IP forwarding on the host machine and then creating a rule in iptables to match the request for http and forward it to guest machine.

I am still interested in knowing the ethernet configuration and VM solution in use and also the guest OS on which you will configure web server :-)

Hi and thank you for your response. I have not implemented the "ideea" yet because all these changes must be fast.

So:
On the host machine i will install Virtual Box and the NAT connection between guest os and host os i think it will be good.

In this situation i will have to turn on IP forwarding on the host machine and then do something like this:

?!

Thank you in advance.

Hi Helyos,

You can setup the connection as per your requirement. NAT is used when you want to share the guest machine IP with the host machine whereas you use Bridge network setting if you want the guest to be directly connected to the physical network.

You can enable the IP forwarding from /etc/sysctl.conf file. Also for more information on iptables you can refer: http://www.yolinux.com/TUTORIALS/Lin...rkGateway.html

iptable instruction that you mentioned looks good to me, just have a query as to why we are using \ before jump target switch.

I would suggest using a bridged connection.

If VirtualBox shows several adapter types for the bridge (it would be under the "advanced" itme on the network adapter page), you may have to test each type to find out which adapter type works.

Once the bridge is established, the port forwarding to the virtual machine can be configured in your router, because the virtual machine will be connecting directly to the router via the bridge.

I have not used these settings for hosting purposes, but, with these settings, I have ssh'd and scp'd into a virtual machine on one computer from separate physical computers on my network.
