I'm trying to decide between a software and a
hardware vpn solution.
Using a vpn appliance
(ex. Symantec firewall/VPN appliance, Watchdog
firebox or Cisco PIX), would you need to connect
these device to a computer running remote access
services for authentication to the internal
network or does the vpn appliance handle that
aspect. Could you please explain how it connects
to the internal network. which is better software
or hardware based vpn's? |

Abel,
The VPN
appliance handles the
remote access service,
however it might be tied
into a backend
authentication server.
Most VPN appliances have
built in authentication
servers, however often it
is easier and more
practical to manage one
authentication server
than two or more. As far
as the difference between
hardware and software
VPNs, they both do the
same from a functionality
perspective, the only
major difference is that
the hardware appliance
has a dedicated device
with an encryption
accelerator that helps
increase throughput for
your VPN traffic. I would
look at the overall
solution and find a
solution that will
accomodate all your VPN
needs.
So if you have
remote workers that need
a SOHO VPN/firewall
device and you have
multiple offices that
need VPN/Firewall
appliances, you'd look at
a VPN company that has
SOHO boxes as well as
larger VPN/Firewall
appliances, e.g.
Netscreen, Sonicwall
etc..
If you're
looking just to connect
remote offices, you can
look at companies like
Cisco or Nortel that have
office-to-office
VPN/Firewall routers.
Hope this
helps.
regards,
Dr. VPNlabs staff |
