Installed SP2 on our nokia 440 this past Sat. night - running FW4.1 on it. +++++++++++++++++++++++++ Clients to one particular web site have been complaining about error messages saying no route to host and proxy errors stating "unable to connect to server - connection refused" type of stuff. Particular clients have experienced this since last Tuesday - at first we chalked it up to possible config issue on their side; however our site began experiencing severe slow-downs yesterday. Page retrieval lasting up to 20-30 seconds. While watching tcpdump on my external interface, I'm seeing hundreds of sporadic messages where my external interface is reporting this back to client ip addresses: icmp: host (our web server's IP) unreachable This will go on for awhile (most recently about 19 minutes) and then all will be fine again. I would think of some type of icmp bounce or something, but this error is being returned to all client ip's - not just "spoofed looking" ips. I wondered about bandwidth problems, but this is only happening to one particular web server. Any comments/insight is appreciated. Regards, Becky p.s. Here's the exact message - sanitized of course because everyone knows that obscurity is really the ONLY way to go. har har (watch the wrap) 05:11.2 208.xx.. > 12.110.xxx.xxx: icmp: host 208.xx.xxx.xxx unreachable (DF) [tos 0xe0] ================================================================================ To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================================================
