I have a small business that uses an ASP (application service provider) for their main day-to-day duties. The office staff is about 12 employees, but they also have about 10 remote users (mostly using OWA or RDP). They are currently using a T1 for internet with 8 channels being used for voice and the rest for data. Since they’ve migrated to the new app, the internet and application performance has come to a crawl. Based on the calculations from the ASP on the amount of bandwidth need per user, they’ve decided to get a 2nd T1 dedicated for the ASP.
So, the question is, aside from spending $3500 on a Cisco 2821, is there a more cost effective firewall solution that can route all traffic destined for the ASP's IP to T1b, and everything else to T1a? Would using 2 cheaper firewalls work if made FirewallA the DG, and then put a static route on it that said anything destined for application.aspcompany.com route to internal interface on FirewallB?
Any ideas / recommendations appreciated.
