Hi there,
i have a load balancer router TL-ER5120 configured with two wan provider with PPPOA protocol.
The provider info login/password are in the modems, each modem have the DHCP active, there's any provider configuration in the balacer.

My problem is the vpn connection.
If i have connect to internet through load balancer and i try to use the a openvpn connection to a remote machine, i correctly establish vpn connection but it's disconnected after 2 minute sistematically (only vpn connetion) .
Note this problem doesn't verify if i connect to internet through whatever other connection.

Please help me!
