You would need to set up your own VPN client on your PC. Anything that comes in through the VPN is classified as ‘Internal’ in the firewall, which already has access to UCP.
I did set up my own windows openvpn client, downloaded openvpn files from UCP, and installed them, etc…
As a reference point, I can access several remote openvpn servers in the office, but for the remote freepbx server, when I try to connect via the openvpn gui, with or without the previously mentioned iptable commands, as you noted, I get:
Thu Jun 21 01:55:07 2018 RESOLVE: Cannot resolve host address: xxxxxxxxx.deployments.pbxact.com:1194 (The requested name is valid, but no data of the requested type was found. )
Thu Jun 21 02:19:02 2018 Initialization Sequence Completed With Errors ( see http://openvpn.net/faq.html#dhcpclientserv )
Thu Jun 21 02:19:02 2018 MANAGEMENT: >STATE:1529561942,CONNECTED,ERROR,10.8.0.4,xxx.xxx.xx.xxx,1194,
The faq section mentioned is of no help. The DHCP Client service is running fine. Not sure where the appropriate log file is located, will look for it later today.
Any ideas off-hand how to fix this so I can connect from windows openvpn gui to openvpn on the freepbx server?
