Perhaps folks on this list can point me to a similar list for routers if this is too far OT.
I have a Cisco 2600 interfacing to my ISP (supplied by the ISP) and it did something today which has never happened before. At a point in time, traffic from the www to *one* of our servers stopped dead. We could still access this server from our local subnet. And www users could still access other servers on adjacent IP addresses just fine. And we could access the outside www using a browser on the impacted server. After troubleshooting everything we could, we finally powered off our router and cycled it on again. Then traffic to the "problem IP address" started flowing again! We haven't rebooted our router since it was installed a year + ago, so this is a bit spooky. I perhaps should mention that the server in question was really a MS Load Balanced array. There is a PIX 520 between the router and server, and the PIX performs the required ARP (if you don't ARP, user's outside the local subnet won't be able to access the WLBS array). The nature of the problem made me suspect that the ARP was somehow compromised. But rebooting the PIX (before rebooting the router) didn't fix the problem. The problem seemed to trace pretty unequivocally to the router. The "ver" information from the router says: Cisco Internetwork Operating System Software IOS (tm) C2600 Software (C2600-I-M), Version 12.1(2), RELEASE SOFTWARE (fc1) Copyright (c) 1986-2000 by cisco Systems, Inc.
