RN102: Changing MTU from 1500 to 9000 & connection problems
I worked on this with ReadyNAS tech support and they were unable to reproduce it. I have a simple network with an Apple Airport Extreme doing the routing and feeding an 8-port Gigabit switch. The swit...
I think the second sentence is not clearly stated in your initial post.
I am guessing that the remote connection is attempting to use the 9000 mtu. That would result in IP packet fragmentation. The effect of that fragmentation depends on the specific equipment on the path to the netgear servers and back. Some equipment simply carries the fragmented IP packets which are then reassembled. Other equipment drops oversize packets and won't fragment. Some will drop fragmented packets because some DoS attacks use them. So the symptoms might vary depending on where the test is run.
Support could potentially look for that specific possibility (and not attempt to recreate your specific symptoms). You could as well if you can configure your setup to do a wireshark trace.
What performance are you seeing on the RN102 (with and without jumbo frames).
