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
