I config OpenVPN service on CentOS 7 and Clients could connect to the server with no problem.
the problem occurred when OpenVPN server connect to another VPN(openconnet VPN).at this time clients lost internet while the server has internet.
I added forwarding rule between OpenVPN and OpenConnect in iptables.
-A INPUT -s tun0 -o tun1 -j ACCET
and vise verse.
what is the reason?
