Hi all,

I hope to be working from home soon, and therefore
connecting to HQ using VPN. What i want to know is, if i
take my works PC home and plug it into my home router,
and then set up VPN (so i can login to the company
network), and i also have my personal home computer
plugged into the same router, how do i make 100% sure
that my home PC cannot be accessed or even seen by the
rest of the company network?

I realise that my personal PC would have to be added to
the company network in order for it to be accessed by
other work PC's, but i was thinking that because my work
PC would be able to see and access my personal PC (both
at home and plugged into the same router), maybe other
work PC's would be able to access my personal computer
via my work computer!! I'm not even sure if that's possible
but i just wanted to check!

The simplest solution would be to enable the built in firewall on it and deny access to everything/everybody.

You will be able to create a VPN connection with your work PC, at home. Remote Desktop could be another solution.

Just because your home PC is connected to the same router doesn't mean that one can read files on the other. You don't have to share files on any PC and of course, you want to make sure that any connection requires a password, if in fact files are shared. I set all my PCs to require a login at boot time. Most people don't and that leaves the shares opened to anyone who can connect.

A more overlooked entry point is if you have a wireless router that is giving DHCP addresses to anyone in the area. I prefer static IPs but I'm one of the few. Don't forget to change the default password on the router. I'm also one of the few who do that too. 99% of the world doesn't.

Thanks for the reply.

What i mean is, can i add my work PC to my home
'workgroup' so both work and personal PC's can access
each other, and still keep my personal PC invisible to the
company network?

For example: If i took my personal PC into an office block
and created a workgroup on it, and then picked a random
PC from the LAN in the office block and added that to the
workgroup...would the rest of the LAN be able to see my
personal PC (the one i took into the office)?

Sorry, that's the simplest way i can explain it!

Your home PC will not be seen by the company network through the VPN that you create on the work PC. However, it still should password protected and you can take HIT's advice about adding a firewall, if you feel that it's necessary.

If you take your home PC to your office, you wouldn't be able to create a workgroup and even if you could, you wouldn't have access to add other PCs for the simple reason that they are probably on a domain or another workgroup.

As a side note, when you are home and the VPN connection is active, you may not be able to share files between both PCs, because split tunneling maybe disabled. My girl friend can't even use her printer when the VPN is active.

Hmmm curious....

At work we use VPN to link several different offices around
the UK to each other. Each office has there own LAN and
in turn, each LAN is connected to one another via VPN so
everyone can access all computers and printers on all
networks...and we can use local printers, so i'm not sure
what's happened with your girlfriends setup!

So anyone got any ideas on how i can network the two
computers without adding one to the company domain??

There are 3'd party applications to allow this. We use Mobile Netswitch here where I work. It allows you to create multiple profiles.

In our case, we use static IP's at work so the "work" profile would have that information in it. The "home" profile would be set to DHCP. You select which to load depending on where you are.

In your case, one would be domain login (work) and the other workgroup (home).

You could set this up with the builtin Hardware Profiles, but you'd have to look up how to do it as I've never done that and can't tell you.

If I were you, I'd take the unit in to the IT department at work, tell them what you want and ask if they could set it up for you.
