<br>Most often, that's the cause. If they're both on private IPs, neither can initiate a connection to the other. If one of them is publicly accessible then a bidirectional connection will be established from the "hidden" machine to the public machine.<br>
<br>Another possible cause if your nodes aren't NATed is just that your firewall is blocking the ports the nodes are using. Look at the "client.port" file in your .tahoe directory to see what port needs to be open.<br>

<div> Is there any configuration I missed for these two nodes seeing each other in one grid?</div>
<div>Why I don't have this problem while I use public grid? I can see all other nodes running and other's directories.<br></div></blockquote><div><br>All (or nearly all) of the pubgrid machines are on public IPs and have the appropriate ports open, so your node(s) can connect to them even if yours are behind NAT or have their ports blocked.<br>
