[arm-allstar] OpenVPN & Hamvoip

[David McGough]

Hi Dave,

On the openvpn server, do you have the "client-to-client" config option 
enabled?

I guess you have the openvpn server in TLS mode, allowing multiple 
clients to connect?? OR, do you have a different topography?

Do you have any iptables firewall setup on the HamVoIP node?

I am trying to use openVPN server running on a Rasp Pi at a friend's 
house.  I have openVPN clients on my hamvoip allstar node and also on my 
win10 PC.  Both the clients successfully connect to the server but using 
Putty on the PC fails  to connect through the server to the allstar 
node.  Both clients show tunnel connections with different ip addresses 
within same 10.8.0.x subnet.  Using the VPN assigned 10.8.0.x addresses 
I can ping from the allstar node to the PC but not the other way.  Any 
troubleshooting suggestions?

Reading through the OpenVPN forums, it does appear there is a client-client config setting, but I didn't have to do any changes to enable it in my instance, so I don't have references other than the 4 websites I used.
