[Solved] Problems routing all traffic through OpenVPN server.

Post by withsmile » Wed Jun 28, 2017 9:06 am

Hello,
My office network contains several VLANs, such as VLAN10(10.7.10.0/24 gw10.7.10.254), VLAN11(10.7.11.0/24 gw10.7.11.254), all these gateways are held by one same core switch.

My computer acesses LAN through VLAN11, and is internet-accessible. Application Server acesses LAN through VLAN10, ip address is 10.7.10.5.

My home network is held by ASUS AC68U merlin(192.168.1.0/32 gw192.168.1.1), and I set up an OPENVPN server on router.

If I triggered OPENVPN client connected to home on my computer, connection between 10.7.10.5 and my computer would be lost, none traffic could be sent to VLAN10. All traffic was routed to home OPENVPN server.

How can I fix the problem ? Thanks a lot for help !
