Hello, I am having some problems with path MTU discovery with a click router.
In this router I fragment and defragment IP-packets. I have a IPFragmenter element that issues a ICMPError-message when a packet arrives that is too big and has the don't fragment bit up. This ICMP-message is configured as ICMPError(WAN1, 3, 4, PMTU 1400, MTU 1400), but still when I try running iperf to test the router, I get 536 as the MTU and not the 1400 I configured. Is there something else I need to do to ensure path MTU discovery works? With regards, David Biot No virus found in this outgoing message. Checked by AVG Free Edition.
