Hello. Trying to set up private p2p network on LAN by blacklisting all IPs exceptintg local. 1st result is all nodes are leaf and do not connects each others. Can I manually set some of them to be peers or ultrapeers? Tried to do that removing blacklist on one node and connecting to global gnutella.net and in that case other private nodes connects just good. 2nd result is linked with addresses, I have 10.0.x.x net and LW says it is behind a firewall at startup even if there is few IN and OUT leaf connections to ultrapeer nodes. All (TCP & UDP 6346) ports are unblocked. Also I can not browse or direct connecto to any of leaf nodes.

LW version is 4.10.3 (4.10.9 on some of nodes).
How to set up stable private network?

Thanks.
