configuring "ip tcp window-size" on the router has nothing to do with the IP packets being forwarded _through_ the router.
a client that cannot complete a TCP session is a classic symptom of an incorrect MTU somewhere and PMTUD failing to perform its task. is your topology really that simple as 3 devices in total? what MTUs are configured? what does a ping with sweep of increasing sizes (with DF bit set) show? are you blocking ICMP traffic? cheers, lincoln. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:cisco-nsp- > [EMAIL PROTECTED] On Behalf Of Hiromasa Sekiguchi > Sent: Wednesday, 5 September 2007 6:22 PM > To: [email protected] > Subject: [c-nsp] About tcp window size > > Hello, > > About below condition. > > [client]------[cisco3745]-----[Web server] > > When TCP connection starts between client and web server, > they can't finish TCP connection. > > The TCP windows scaling is configured with web server. > > So, should we change the tcp window size on cisco3745? > > e.g. cisco3745(config)#ip tcp window-size 750000 > > Regards, > Hiromasa _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
