I have an issue where the performance of the port forwading seems to have an slow troughput problem on the ER8411. Any firmware version (have just installed the beta too)

I have a 1Gbit / 1Gbit WAN link connected to EthWan port 4.Behind that is a 10Gbit network connected to the SPF+ port 2 using a Mikrotik 10Gbit SFP+ (there are other components in the network, but excluded for simplicty)

PC1 runs Iperf and teh ER8411 has a Port Forwarded of port 5201 to that PC

Network has an OC200 hardware controlller to run it.

1) PC1 speedtest to Ookla internet gets 1g/1g full speed result both directions.(900+ / 900+)

2) PC2 iperf tcp connection to PC1 gets 10g result both directions (9000+ / 9000+). So we now PC1 has plenty of speed.

3) However Iperf from WAN to PC1 gets maximum 600 in both directions (even with more than 4 threads of Iperf)

4) If I change the gateway back to a TP-Link ER605 gateway, WAn iperf to PC1 gets full speed 900+ both directions.

Also note - If I move off the LAN SPF+ 10g and connect the cable instead to a 1g lan port on the ER8411, the iperf from WAN goes full speed.

Is there some setting to help with this packet port forwarding rate or a fault of some kind perhaps on the ER8411 specifically do do with the 10G SFP+ port?

I'll soon have a 10g WAN to test again on too.

Some other feedback too

- Can we set other SFP+ WAN rates other than 10g or 1g? - eg 2.5 or 5 - the SFP+ module supports it but the ER8411 only has 10 and 1 as options

- Can we enable the fan to be forced on? The SPF+ is really hot and having the fan running would help (temp of the router reports 59 degrees, but the fan is idle)
