I would be grateful for suggestions to solve the following connection
problem.
In the following description, D stands for 192.168.1
My router, D.1, has a control panel that identifies the following
ethernet connected devices:
192.168.1.10 f0:2f:74:1f:d0:99 y
192.168.1.16 b8:27:eb:50:44:91 y
192.168.1.3 f4:30:b9:83:84:1c y
192.168.1.6 74:03:bd:0c:b0:38 y
192.168.1.9 40:16:7e:b4:09:e2 y
y indicates that the device passes traffic to the WAN
My laptop, D.3 shown the following devices by ip neigh:
192.168.1.1 enp1s0 c4:ea:1d:e4:27:a2 REACHABLE Y
192.168.1.10 enp1s0 f0:2f:74:1f:d0:99 STALE N
192.168.1.6 enp1s0 74:03:bd:0c:b0:38 STALE N
192.168.1.9 enp1s0 40:16:7e:b4:09:e2 STALE N
Y/N indicates ping success.
D.3 "knows about" D.6, D.9 and D.10 because they are in /etc/fstab as a
result of previously successful connections.
D.9 acts as a server and shows the following by ip neigh:
192.168.1.1 enp2s0 c4:ea:1d:e4:27:a2 REACHABLE Y
192.168.1.10 enp2s0 f0:2f:74:1f:d0:99 REACHABLE Y
192.168.1.16 enp2s0 b8:27:eb:50:44:91 STALE Y
192.168.1.6 enp2s0 74:03:bd:0c:b0:38 STALE Y
D.10 is my main work PC, and shows the following via ip neigh:
192.168.1.1 enp5s0 c4:ea:1d:e4:27:a2 REACHABLE Y
192.168.1.16 enp5s0 b8:27:eb:50:44:91 REACHABLE Y
192.168.1.6 enp5s0 74:03:bd:0c:b0:38 STALE Y
192.168.1.9 enp5s0 40:16:7e:b4:09:e2 REACHABLE Y
D.6 ia a NAS box that both D.9 and D.10 can and do write to.
D.6, D.9, D.10 and D.16 are connected to D.1 via an 8-way Netgear hub
My problem: D.3 cannot reach D.9 or D.10, and neither D.9 nor D.10 can
reach D.3, despite all being connected to D.1
(I hope the attempt at tabulating this data survives the translation to
other mail clients)
