MII 12.1.8 not connected to ECC 6

Question

Hi,
I have already configured successfully another instance of MII/4.6C (only idoc listener) and now I'm trying to link an instance of MII 12.1.8 (NW SP5) with an ECC 6.
I cannot even read BAPI list from SAP JCO Interface action inside a MII Transaction
I have configured the JCO Connector from System Connection Editor of MII and the credential alias usign a SAP_ALL user (to avoid rights issues).
I tried a ping from MII server to SAP AS and it's ok.
I already tried to reset JCOProxy and restarted my CE, but nothing...always getting this error
JCO Proxy Error: Connect to SAP gateway failed

Did I skipp soemthing I should do NetWaever side? My understanding ti was I could link MII to ECC (to call BAPI) configuring connector inside MII only (even if, probably, calls are flowing through NetWeaver layer). I feel it can be something related to NW side (maybe the message server) but I really don't know what to touch.
I didn't yet installed licenses (but three months still didn't pass)...can be this the reason of my issue?
I also tried to configure IDOC listener inside NetWeaver, trying to register it to SAP Gateway, but also this link attempt failed...
it is something like the two world aren't connected, even if the server is pinging to SAP AS. No firewalls...
any idea?
best regards

...mmm...not working, saying...

but the link you posted is interesting...if I well understood, every time there is H the current "system" is sending to the the first H it has the next Hs (removing the first H and checking a sort of internal firewall to grant connection). Mainly, connection path is built system by system, step by step...
S and W are optional and to be specified if we need a service different from default and a password
Doing crazy attempt:
If I'm running my MII transaction test from my laptop, do I have to set up my first "connection step" to the host which is running MII instance? I mean something like:
/H/<MII Server IP>/S/50000/H/<SAPROUTER IP>/H/<ECC IP>
This way I noticed that in the Java AS, under ICM/Connections READ REQUESTS messages are created.
But log is saying request is too big.
