Hi there,
I have read the Networking FAQ and also done a search but can;t seem to find what I am looking - which surprises me a little because I can;t believe I am the first to have this issue...

Anyway,
I have Mac 10.8.4 as the Host
and I have Windows 7 64-bit as the Guest.
and I am using Virtual Box 4.2.14

The short of it is - I have MS-SQL installed on the windows 7 guest and would like to access it from the Host (Mac).
I am attempting to get everything working in Bridged-mode.
Because I am also using the VM for accessing other MS-SQL servers using the Guest OS's SQL Server Manager.

Lastly - and unrelated;
If I choose "host-only" I get told that I have chosen an invalid setting and cannot click OK.

As always - Thanks in advance.
- Gavin

You have said what you're trying to do, but not what your problem is.

I cannot connect to the SQL server on the guest from the host.

Can you ping or connect with any other program to the guest from the host? Did you disable firewalls & stuff?

Have you set the guest to use bridge mode? Does it have an IP in the same IP subnet as the machine you are seeking to contact it from? If in doubt, post an ipconfig of each machine.

Thanks everyone - and sorry for the delay...
I "think" I have a better understanding of the issue - but of course being completely new to VB - could be wrong!

At (my personal) home my Host, get s a 10.0.2.xxx private address.
I have port forwarded 127..0.0.1:1433 to 10.0.2.15:1433 - and so at home it works like a charm.

At work it gets a 192.168.x.x address.
The guest OS (seemingly) always gets a 10.0.2.15 address regardless - which places it (at work) in a different IP range.
So I think this is why I am not connecting to my SQL server when at work.

That's the information I have... not sure if it helps or not...

The network is set up for NAT.
Here is the ifconfig from the problematic host (at work);

I suppose what I need to know is how do I ensure that my host and guest are always on the same static LAN so that I can set an appropriate port forward rule?
Or is there a way to do this dynamically, so that it doesn't matter what IP Address the Host gets?

As always - thanks very much for your help - I do appreciate it.

If that's what you've put in Virtualbox NAT forwarding rules, remove the IPs completely, and only keep the ports.
Then from your host, you should be able to use 127.0.0.1:1433

Hi Again - and thanks for the help.

I have altered the port forwarding rules as you suggested;
Removing all IPs (Host and Guest)
And just having port 1433 -> 1433

I have restarted the Guest (and even the host) after making the changes.
But... unfortunately I am still unable to connect to the SQL Server from the host to the guest.
I simply get a network timeout error.

Do I still have the network set as NAT?
reading the docs - I would have thought that I wanted "host-only" as the Network choice - but I get told it is an invalid choice.

As always thanks!

Gavin.

For all those that replied - thanks for your help.
I have solved my issue.

Once I altered the port forward rules to just be for the PORT only, from a VB perspective, it was all working fine and dandy.
The solution to my connection issue was ensuring as appropriate rule was in place for the Windows Firewall to allow connections for port 1433.

Again - thanks for all your help!
