I have set up several ubuntu VMs using virtualbox. Right now I'm using network type as NAT and have access to it from the host machine, but what are the network changes that are needed to access these VMs through putty from other machines that are connected to the same network(wifi) ?
figured it out myself, first turn off the VM.
- enable two network adapters
- 1) host only - to connect between host and guest machines
- 2) Bridged network - to expose the vm to the network and assign ip address for each vm through dhcp
note: In my case I used vagrant tool to spin up my VMs, hence assigned fixed private ip to each vm,by enabling host only..I could do a headless start and then log in to VMs through putty(using fixed private ip) and get the dynamic bridge network ip.

I'll make this quick.
I have created a virtual network by setting several VMs to use HostOnly VMnet1 as their network adapter.
I then added a pfsense virtual machine firewall into that same network and configured it to allow traffic to the internet but block to/from my real home network.
That way - my virtual network can connect to the internet even though it is in host only mode.
The thing is, I need to manually set the DNS and Gateway of each machine in VMNet1 to the VM firewall to allow them to communicate since all communications must flow through it.
I was trying to figure out if I can do this automatically. When I go into Virtual Network settings in VMWare Workstation 16, the only options I can set are the subnet and available IP Scope. There is no option for default gateway or DNS here. Can this be done?
Do you have the ability to run a DHCP server on the PFSense firewall which is connected to the VMNetwork? If so, either Windows and Linux VMs that have their NICs set to DHCP, would get the IP, DNS and GW from the DHCP.
I have a virtual machine instance running on Google Cloud Compute Engine — a preemptible free-tier CPU running Ubuntu 17.04. The end goal is to connect it to a MongoDB running on my local machine, a 2015 Macbook Pro (OS 10.12.6). But first, I've been trying to ensure the VM can reach my Mac via ping.
Running ping <VM's external IP> from my Mac works.
pinging my Mac from another Mac on the same wifi network works.
Running ping <Mac's IP> from the VM via the browser terminal does not work.
I've disabled my Mac's firewall. I've also configured my VM's firewall rules to allow all inbound and outbound traffic, to no avail:
ingress firewall rules, egress firewall rules
How might I get this instance to ping my Mac successfully?
Does your Mac's IP address begin with 10., 192.168., or between 172.16. and 172.32.? These are private addresses only reachable within your Mac's local network, which is (part of) why GCE cannot reach your VM.
This is part of a very common configuration. An ISP only allocates one (or a small number) of IP addresses to your home or business. A router on the network performs NAT to share that IP addess between computers on the local network, which instead use private IP addresses for themselves. As the router doesn't know what to do with the inbound MongoDB traffic, it blocks it.
There are two common ways around this that are usually found in your router settings:
"port forwarding" where you tell the traffic to forward all traffic on port 1234 to your Mac. This can get MongoDB working, but not ping.
If you have whole extra IP addresses, "DMZ" where your router directly forwards an entire extra IP to your instance. If you have only one IP address this is not an option as that IP is needed to be shared for other devices on the Wifi.
You likely also have a firewall on the router. If you use a DMZ or port-forwarding you must make sure that firewall allows traffic through too.
That said, I'm not sure that this is a sensible thing to do. Opening up your local network to the internet can create major security issues, plus it is likely unreliable more expensive (free tier only provides 1GB egress/month, your db traffic could exceed this).
Actually running MongoDB on instances within GCE is almost certainly a better option in every regard for you.
So I know to access my host computer's localhost from virtualbox, I can hit up the IP 10.0.2.2. However, I need to access a different IP on my host. I've set up another local site running on host at 192.168.7.9. How do I hit this IP from inside virtualbox? Thank you.
Your virtual machine is probably in NAT networking mode.
You need to change networking to Bridged and choose the same Network adapter
like i did on the image below...(on my laptop wifi NIC is Intel Centrino, yours is probably different!)
Then your virtual machine will be directly connected to the same network as your laptop and it'll have a similar IP address as your host... 192.168.7.x
and then you can connect to any IP address you want!
This would be the simplest way to do it.
I installed Vsphere 6.0 on a VM workstation 11 and on booting it gave me an IP address (static) - 192.168.254.XX and i used the same address to log into the Vsphere Client.
In Vsphere Client, I created 01 VM. My ESXI machine in workstation is connected to physical NIC (Bridges connection) and is supposedly getting internet access.
How will the internet connection be routed to Vsphere VMs via ESXI system on VM Workstation. As per my understanding, the Vsphere client where my VMs are installed, is interfaced to ESXI system. So, do i need to NAT my NIC to the ESXI IP address or to my ISP address (DHCP)??
i want to give internet access to my VMs in Vsphere client How should i go about it? My internet connection is a DHCP based system.
Also, how to go about configuring DD-WRT to distribute internet to various VMs??

If you create two virtual manchine, you should create a virtual NIC for each, with different IP addresses. So you end up having 3 IP: ESXI native IP, VM1 IP as VM2 IP. If you want to access your VM from outside your lan, you should open the port on your router and then NAT to desired VM IP. Hope this is what you need.
I have a Host with VirtualBox installed and Guest installed (both with Windows XP SP3).
I do have connection between them. And also the guest have an internet connection.
I can connect via Remote Desktop Connection from Host to Guest, but I also want to be able to connect to Guest from any other PC. If can, how to achieve this?
Guest is using 2 network adapters, one NAT for sharing the internet connection and then one Host-only to be able for both machines to see each other on the local network.
Assuming you have an Internet router providing access to your ISP...
Change the VM networking from NAT to Bridged.
Check that the guest still has Internet connectivity after rebooting or ipconfig /renew.
Configure the router to give the guest a fixed IP address. (Typically, the guest can still use DHCP but the router is configured to give the guest the same IP address every time.)
Determine which ports and protocols needed to connect with the guest. E.G, TCP on port 3389 (RPD) for Remote Desktop.
Configure the router's "port-forwarding" feature to route external connections to the IP address of your guest. You can designate a different port for the external connections but that might not get through firewalls between the remote computer and its ISP.
Determine the external IP address of your Internet router.
Connect from the remote computer to the IP address and designated port.
