I have an issue with my network setup and could use your assistance. I have configured forwarding on the ZeroTier web portal (ZeroTier Central) as follows:
-
My network IP range is 192.168.194.xxx
-
Configured forwarding rule: 10.10.10.0/23 via 192.168.194.196
-
Forwarding is done using the ZeroTier adapter (ztppi4m2bo) on 192.168.194.196
From my Windows system located at 192.168.194.1, I cannot receive ICMP echo replies when pinging 10.10.10.165. However, I can successfully ping the router at 192.168.194.196 and ping 10.10.10.165 from the router itself.
Using tcpdump, I confirmed that the ICMP echo requests are reaching 10.10.10.165, and the corresponding echo replies are being sent back to the router at 192.168.194.196. The tcpdump output from 192.168.194.196 demonstrates that the packets are being routed to the ZeroTier adapter (ztppi4m2bo).
However, on my Windows system at 192.168.194.1, I am not receiving these ICMP echo replies. I have already disabled the Windows Firewall, but the issue persists. When analyzing the network traffic with Wireshark on 192.168.194.1, I do not see any packets received from 10.10.10.165.
The output of the ‘route print’ command on my Windows system shows the following relevant routes:
-
10.10.0.0 255.255.255.0 192.168.194.196 192.168.194.1 291
-
10.10.10.0 255.255.254.0 192.168.194.196 192.168.194.1 291
These routes seem to be automatically set up by the ZeroTier driver.
I would greatly appreciate any guidance or suggestions to resolve this issue.
