My RVS4000 V2 (v2.0.3.2) will not transmit jumbo frames between any 2 lan ports.
Endpoints: Win7 pc, mtu 9216; Synology DS212j configured for jumbo frames (MTU listed as 9000)
Lan ports on the RVS4000 are configured for Max Frame 9216 (only port 1 can be configured, others are grayed out but show 9216).
When the listed endpoints are connected via a Netgear GS108 switch, ping -l 9000 works, and file transfers appear to be limited by disk speeds (i.e. >60MB/s).
When the listed endpoints are connected to rvs4000 lan ports, pings over 1500 bytes fail, and file transfers never connect.
I've tried disabling IPS, QOS and even the entire firewall, and both with and without flow control enabled.
Is there something I'm missing?
