Can't access guests from non-host computers on LAN

[macman4400]

I have a Windows 7 Host running a few guests on Bridged mode. Each of these guests can access the internet and ping every other box on my network, but no other boxes can access or ping any of my VMs. My router won't assign any of them IP addresses with DHCP so I have them all configured with static addresses (192.168.200.200 with gateway 192.168.200.1 (my router)).

On one of my VMs (CentOS) I have an apache server running that I use for web development and I want to share that to my LAN. I followed the general steps to allow this, but I can't access it from my entire LAN. I can access the site from all of my VMs and my host, but nothing else.

I will post any other requested information.

Thanks!

Edit: I can access the website on my Apache server from my windows 7 host.

I have them all configured with static addresses (192.168.200.200 with gateway 192.168.200.1 (my router)).

Each guest should have a different IP address.

Sounds like you have a firewall issue or Virus software that is filtering the access.

[macman4400]

Yes, their IPs are 192.168.200.200, .200.201, ..., .200.205.

I completely shut off my Win7 antivirus and firewall and it still didn't work.

Keep in mind each of these VMs has full access to the internet, each other, and my host.

[Perryg]

Still in Bridged mode they all appear to be just another PC on the LAN. If the others can not access them & there is no filtering going on then it must in in the router.
Are they all in the same subnet as the other PCs?

[macman4400]

Yes. Everything on the router is in 255.255.255.0.

I just ran nmap on my other computer and found everything I have hooked up except my VMs.

Edit: I can access the website on my Apache server from my windows 7 host.

I can't think of any reason why that would happen. As far as the networking software is concerned there is no difference between the host and any other machine on the LAN. Could you attach the ifconfig of your Apache server and that of a LAN machine which cannot reach the server?

[Perryg]

Post the results of ifconfig -a or ipconfig /all if windows from one of the guests as well as the following:
From the host command window VBoxManage list bridgedifs
Note: you will need to be in the folder that has VBoxManage.exe on a Windows host if you have not set up an environmental variable (path statement) for VirtualBox.

[Perryg]

Sorry Bill, Didn't see your post. I will leave it to you.

[macman4400]

Here are my configs:

My Win7 Host can ping and access my VMs. My VMs can ping and access my Win7 Host.

My VMs can ping any computer on my network, but none of them can ping my VMs. My VMs can log into the router, access the internet, etc. My host can see the websites running on my VMs.

Look in c:\program files\Oracle something.... That is where all of the VirtualBox files should be.

The only common thing that I see so far is the router. Can you post an ifconfig or ipconfig from one of the other LAN clients? Other than that you would need something like wireshark to see what or where it is being filtered/stopped.

[Perryg]

Are you using a tunnel? Any VPN software running?

What else can I do at this point? In the past I have run Apache servers on computers on my network without virtualization and they worked.

Edit: No tunnel or VPN on my Host or Guests.

[Perryg]

I don't know. Everything checks out so for so it must be something that I can not work on remotely. I would look at the router since it is the single point of access or use wireshark to find out why and where the path is stopping.
