Do you mean an external machine can ping and have responses from the gateway, but no responses from the nodes? and also the nodes can't ping each others ? Is the router connected with the switch(mikrotik) or the switch it self is the gateway ? And can you try pinging IPv6 link-local addresses to each others (although it should not matter)? Can you share some tcpdump captures while pinging? While I'd suggest you connect two of the three nodes with twisted pair and this is a minimal setup to narrow down the problem. -- You are receiving this mail because: You are the assignee for the bug.
