My network is consisted of multiple VLANS:
management 10 (192.168.10.0/24)
wired clients 100 (192.168.100.0/23)
wireless clients 200 (192.168.200.0/23)
and the VPN subnet (192.168.30.0/25)
I am able to connect to the VPN successfully, and I am able to ping all the default gateways for each VLAN. However, I do not see any pattern with what I can ping and what I cannot. I can ping a few clients in VLAN 100, and a few in 200. The few that I can ping are laptops, desktops, mobile phones, APs, etc. But I also cannot ping a few desktops, laptops (of the same model and OS).
For example, right now I am trying to remote desktop from a VPN client into a wired windows desktop on VLAN 100. I allowed remote desktop connections on the windows machine. I can remote into it from another windows machine on the same VLAN, but not from the VPN client.
I just barely implemented this network less than a week ago, so I have not added any firewall rules. All connections between SSIDs are allowed. Is there something else I can check for?
Solved! Go to solution.
Could you add a rule to allow inbound traffic from the subnet allocated for client VPN.
My guess - Windows firewall on the machine you are trying to access. If you turn Windows firewall off on the destination machine does it work?
Yes, I am able to connect to it without the firewall. Is there a certain rule that I have to add to the host's firewall?

That worked! Thank you so much for your help!
can you run a packet sniffer such as Wireshark while having a continuous ping -t to your file server
you can check the issue
also do you have VLANs? incorrect VLAN or IP address in the file server can cause this issue.
