I have installed MS Loop-back adapter and have given it a static IP: 10.10.10.9
my laptop is configured as 10.10.10.30 , and my gateway is 10.10.10.1
i can ping the loop-back NIC from my laptop, but not from any other machine on the LAN. i am trying to beat the 65k port limitation by seeing if i can have virtual IP addresses on one machine and each can then give me 65k ports
thanks.
By very definition, you CANNOT talk to a loopback adapter from any other machine but your own.
If on Linux, you could bridge it to a physical adapter, such as eth0, but why would you want to do that?
Take a look here for setting up IP alias on Windows (disclaimer - I don't own any windows machines, so can't really verify this).
You can ping your Loopback interface from LAN by installing Remote and Routing Access role on the server. After installing the R&S role on the server , configure LAN routing feature. It will start pinging from LAN. I have done this practically in my environment.

In GNS3, I have configured the DHCP pool on the router R1, and I have a vmware VM (Ubuntu 16.04), another router R2 and VPCs are connected to R1. The R2 and VPC can get their IP address without a problem, however, the vmwareVM can't receive the IP address.
Note that:
the station is configured as host-only
the connect a host virtual adapter to this network is checked
the VMware Workstation DHCP Server is turned OFF
No configuration on my local PC Network Connections (DHCP)
Once I type the command dhclient eth0 to get the IP address from dhcp, it freezes and returns nothing and no IP address is assigned.
I want to know what is the problem that causes that issue and how to solve it.
Thank you.
My mistake was in the configuration of my VMware network adapter (VMnet2) in my network adapter in my host.
so in order to get the IP address from the DHCP router: I did the following steps:
Create a virtual network (VMnet2) in the virtual network editor
of VMware.
I checked the "Host-only" option
I checked the
"connect a host virtual adapter to this network" option
Uncheck the "use local DHCP service to distribute IP address to VMs".
Do not change the default configuration of the VMnet from your
network connexion options.
I hope that will help someone has the same issue as me
I want to forward a port to a VM. However i dont want the VM to be behind my host PC, i want it to be connected directly to the router so that packets coming on that port go directly to the VM without passing through my host PC.
In other words, i want the VM to look like any other machine on the network.
EDIT: i used bridged adapter, but i couldnt make it connect to the network.
Thank you
The VM will use the Ethernet port in all cases and the OS in it.
Typically if you have Windows and a VM with a bridged port, you will see the traffic flow when you take a capture on the Windows machine. IP won't be the one from the Windows machine but the traffic, like said, will flow through the same physical interface.
Secondly, you need to use a bridged adapter. For the details you can find help here: Bridged networking not working in Virtualbox under Windows 10
I currently have a virtual machine running on Windows. The VM is running Linux and has a virtual box network between the windows machine and the linux machine. The VM is running a application that I want to be able to connect to from the outside world.
To make this possible I tried port forwarding from the windows internet interface, to the windows virtualbox interface. Finally I created another port forward from the windows virtualbox interface to the Virtual machine interface.
netsh interface portproxy add v4tov4 listenport=5000 listenaddress=10.11.65.103 connectport=7890 connectaddress=192.168.56.1
netsh interface portproxy add v4tov4 listenport=7890 listenaddress=192.168.56.1 connectport=5000 connectaddress=192.168.56.101
So if I connect to the 10.11.65.103:5000 on the Windows Machine it will be the same thing as connecting to 192.168.56.101:5000 of the VM.
[Win Internet Intf] [Win VM Intf] [VM intf]
10.11.65.103:5000<----->192.168.56.1:7890 <------> 192.168.56.101:5000
Unfortunately, this is not working for me... Can someone tell me why? Am I using port forwarding correctly?
If you use a bridged network adapter your Linux machine should pick up an IP off the host network (if you have DHCP enabled on the network, or set a static IP on the linux box). Then you should then not need the port forwarding.
If you cant use that approach and are using a NAT adapter (which it looks like you are), then you will need to enable port forwarding within VB. The details are in section 6.3 of the VB Help with this in place you should only then need the first port forward, VB will be doing the second.
Dont forget to make sure the relevant firwalls on the Windows and Linux machines are open.
I'm new to dnsmasq and networking isn't my strong point, hopefully i'm missing something simple.
I have a Ubuntu laptop running dnsmasq. The laptop's WiFi is connected to the Internet, the laptop's ethernet is connected to a LAN.
Plugging my machine into the LAN I am assigned an IP address by the laptop. Accessing www.google.com on my machine gets picked up the laptop and i'm served the laptops Apache page, which is my desired result. The problem is I can't access any other website, Destination Host Unreachable.
I'd like the laptop running dnsmasq to allow my machine to resolve DNS queries normally and only be restricted when accessing www.google.com.
My dnsmasq.conf is the default except:
address=/www.google.com/192.168.0.1
interface=eth0
dhcp-range=192.168.0.50,192.168.0.150,12h
I've a feeling it might be related to the IP settings on each network?
The WiFi has a static IP 192.168.1.55 taking to the router at 192.168.1.1 and the DNS server at 192.168.1.10.
The ethernet is configured manually with an IP 192.168.0.1 setting the router as the WiFi IP 192.168.1.55 and the same for the DNS server 192.168.1.55.
Thanks in advance for any help.

After a lot of fiddling, this was related to iptables and not dnsmasq.
I have a windows 2003 VM running on my windows xp machine.
The machine name of the VM is itdom.domain.com
The windows xp host machine is disconnected from the LAN.
I want to be able to connect to the VM from the host and vice versa using there computer names. For example the URL http://itlab.domain:7080/domainsm must be accessible from the host computer.
Is there any configuration that I can do on any of the machine to do this.
Just because you have no physical network connection doesn't stop you setting up networking on the host and guest machines. One way of doing this is to add an IP address to the host machine's physical network port and create a bridged network on that port so that the guest can also see it.
You don't say which VM technology you are using, but in many of them you can setup an internal network between the host and guest. All you need to do then is edit each hosts file to add a hostname for the IP address of the other machine. You may also need to configure firewalls to allow access between the two.
No doubt there are also other ways to achieve this.
