We are in a cluster environment. We have compute nodes with jumbo packets enabled and a MTU of 9000. We are running into some issues in tracebacks to an address outside of our lan, where jumbo packets are being dropped due a firewall with a standard MTU size of 1500. Is there a way to limit or fragment outgoing packets to this specific address to a smaller packet size without having to down and reconfigure the NIC? I was thinking it might be possible to generate a VNIC with a smaller MTU and bridged to the higher MTU physical NIC, but I'm open to any other suggestions.
