Hi Michael-
Here is the skinny on something that can be a quick
fix to what you are requesting.
If you are a big time scalper, who is trading size on
the market 100+ contracts of the e-mini or such, then
I wouldn'f recommmend this particular piece of
Hardware. However, for the average @ Home trader
trading a mere 1 to 5 contracts this is an affordable
solution.
the Nexland ISB Pro800 Turbo offers features like
Network Address & Port Translation (NAPT) Firewall,
Virtual Private Networking (VPN), load balancing over
its two WAN ports, and even failover support over a
serial analog modem connection.
