Connecting to the office from home | ||

Telecommuting, or remote access, is one of these things weve discussed for years which has never really taken off.

The idea is great, you can work without going into the office, saving hours on the road commuting. You can check the accounts or diary without driving in, staff can login while away from the office and your accountant and IT guy can check things without charging you for their travelling time. It's a shame it never really took off.
With ADSL
and cable broadband connections now common, remote access for small businesses
is realistic. A successful setup requires three factors.
A fixed IP address
Every Internet connection gets its own address, this is essential
for the computers to talk to each other. Most Internet plans provide a
dynamic IP address, which means the address is just pulled out of the
group owned by the ISP. For remote access, a static address is required
so the remote computers know where to look.
Software
There are two types of remote access. Remote control
and VPN (Virtual Private Networking.) Remote control allows a remote
user to take control of a machine and is best for technicians and after
hours access. A VPN connection is effectively
a network connection where the remote computer is connected as if it was
in an office.
Virtual Private Networking allows the remote user to logon just like anyone
else on the network. The software to allow users in is built into Windows
NT, 2000 and 2003 servers as well as Windows XP Professional. Most systems
can login with the correct setup.
Security
Obviously, if you are making a door onto the net available, security
is essential. We recommend a firewall or router with VPN features and
strong password protection.
Its also a good idea to restrict remote access only to certain users.
If your office is the type where no-one bothers too much about passwords,
youll have to change this before setting up remote access. Remote
users should be restricted on what they can access when they log on. Its
a good idea to setup a proper security system before allowing remote access.
Once remote
access is setup on the server, its a matter of setting up the individual
clients. If you are using the built-in Windows VPN software, its a matter
of creating a new connection in the Network Connections folder. For remote
control software, youll receive a viewer or client program to install
as part of the package.
Telecommuting and remote access is now affordable and, once set up, simple to use. There are cost and some expertise required in setting it up but for many small businesses the costs are worthwhile. If you think your business will benefit from it, then talk to your IT consultant.
