My problem was the old Cisco IOS [Version 12.3(8)YI1] that came installed on my Cisco 1811 router I purchased in March 2006. I believe this is still the default shipping version for this router, so anyone who buys one really needs to get a Cisco support contract for it from a Cisco reseller so they can download a new/working IOS [Version 12.4(9)T1 was the most recent as of this email and was the one I used].
