Supported Hardware Solution Recommendations Please

[RonSenykoff@xxxxxxxx]

Hello All,

We are moving all our servers to a colo
facility and need a solution for firewall / QoS that can handle multiple
subnets of IPs routed to it. We expect to ramp up to a high volume of traffic
as we migrate our users to Citrix. Unfortunately, the higher-ups are not
willing to go with an 'unsupported' product even though I can demonstrate
failover, etc. So, I figure there may be some companies offering a linux-based
solution with support. Hardware based is preferable... Basically, they
want something that if it fails, they can call up somebody on the phone
and get it figured out. We need redundancy of the products as well. I'm
thinking a firewall / bridge config using spanning tree for failover.

Any suggestions (simply URLs to sites
even) are greatly appreciated.

Best Regards,
-Ron
