Hello,

I have replace the TL-ER6120 v3  with a ER8411 1.0.2.

I'm now facing front of big issue with range ports forwarding needed by my server.

In controller mode (OC300 5.7.6) :

First bug when I tried to add  UDP ports range forward from 9000 till 10999, the controller replied that the start port must be lower to the end port, and I was forced to use 2 separates rules to add all those ports, 9000-9999 then add 10000-10999.

But even this bug forms turn around, the tests to check the reals ports mappings failed with showing shuffle externals ports opened (ex. 9000 IN->>29929 OUT), and I can’t get the right access to the server if  behind the ER8411.

In Standalone mode:

I didn’t met the bug of non acceptance port entry 9000-10999, but the mapping ports issue is the same than in controller mode, wrong ports opened EXTERNALY..

Temporary, I have now reconnect the TL-ER6120 in front of/before the ER8411 to make the server again online, as I don’t have any issue with his ports mapping settings, and I have connect the ER8411 behind/after the ER6120. (using 2 NAT is in despite a temporary solution)

I can confirm that ER8411 can correctly manage/translate/forward ONE port mapping, but in my case it can’t be a solution to setting hundreds ports opening one by one.

Maybe I'm missing out something here with my settings ?

ISP directly connected to Wan/Lan4 port ER8411 and got dynamic IP

Server directly connected to Wan/Lan8

DHCP running from ER8411 -- IP reserved for the server 192.168.10.50

NAT-Port Forwarding rules:

Does anyone got some issue with large range ports forwarding with the SDN5.6.7 and ER8411 1.0.2 ?

Best Regards,
