Hey people,
We're moving to a co-locate environment, and my client wishes to use a VPN
tunnel between 2 Nokia ip440's running NG PF3 to connect the internal
Network to our DMZ networks at the co-locate space about 50 miles away.
l'm pitching for a dedicated T1 line to our IP440 at the co-lo, thereby
offering best security, and stability, without the need for an extra
firewall (with the associated licensing/support costs), whilst they wish me
to use an available shared T3 connection with an encrypted tunnel to our
co-lo firewall.
Is a VPN tunnel hard to set up? and once set up, how stable is it? Will we
have to manually reconnect/authenticate often? or would it be rock solid?
Another question is throughput performance. Although mostly we will not be
transmitting lots of data, late at night l will be backing up about 20 gigs
of data every week or so. How much bandwidth does encryption use (DES3)?
Would this large throughput make the tunnel less stable?
Thanks in advance,
Alan
