Some network computers not visible/not pingable

Post by rightvision » Fri Oct 20, 2023 4:59 pm

SoftEther connects fine and no errors are shown, but some of the computers in the private network do not show up and also ping does not work.

After I connect I can see 10 systems (Advanced IP Scanner), but there are 14 systems online.

Allow ping in the firewalls.

Ping is allowed everywhere and one system is a debian linux without any firewall installed (for testing) - as the external firewall filters

Can you successfully ping the other 13 from the Debian?

If yes, connect a VPN client and post traceroute logs from it to:
1/ ping-responding PC
2/ ping-non-responding PC

While at it, post as code from the SE VPN server:

Code: Select all

netstat -r
ipconfig /all
arp -a
vpncmd localhost:port /server /password:*** /cmd BridgeList
vpncmd localhost:port /server /password:*** /cmd RouterList
vpncmd localhost:port /server /password:*** /adminhub:@@@ /cmd StatusGet
vpncmd localhost:port /server /password:*** /adminhub:@@@ /cmd NatGet
vpncmd localhost:port /server /password:*** /adminhub:@@@ /cmd SecureNatStatusGet
vpncmd localhost:port /server /password:*** /adminhub:@@@ /cmd DhcpGet
vpncmd localhost:port /server /password:*** /adminhub:@@@ /cmd AccessList
//replace: 'port' with number; *** with SE admin password; @@@ with VPN hub's name

If applicable, VM host of the VPN server:
netstat -r
ipconfig /all
