Hi,
I'm not a Network Engineer by trade, so please humor me w/ the following :)
I'm currently working within an institution that has about 250 users connecting to the Internet through an ISA 2006 proxy that passes connections through an old Cisco 1760 and on to a local ISP. At the moment, we're seeing a large number of connections being denied during peak hours. ISA logs show max simultaneous connections hitting ~12000. I highly suspect the 1760 is the bottleneck. This leads me to three questions:
1. Is it reasonable to suspect the 1760?
2. How could I confirm in IOS that connections are being blocked?
3. What would a reasonable replacement device be (for the 250 users)?
The connection from the 1760 to the ISP is running at 8Mbits
Thanks very much,
