Hello everyone,
Currently I use the NetworkManager tool for configure my wire connection. It works fine expect when I trys to setup a VPN connection. Here is my ifconfig output:
| Code: | enp5s0f2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

The interface "vpn_vpn" is created by the vpn client (Using Softether VPN because I need ipv6 support and it is easy to configure) and the ip address for vpn_vpn is obtained by using "dhcpcd vpn_vpn".
And here it is the route table output:
| Code: |
hasee-k670 vpnclient # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 59.66.90.1 0.0.0.0 UG 100 0 0 enp5s0f2
default 192.168.7.1 0.0.0.0 UG 205 0 0 vpn_vpn
59.66.90.0 0.0.0.0 255.255.255.0 U 0 0 0 enp5s0f2
59.66.90.0 0.0.0.0 255.255.255.0 U 100 0 0 enp5s0f2

It can be seen that exists a default gateway entry for gw 59.66.90.1 and iface enp5s0f2. And the network traffic is still go through the enp5s0f2 interface rather than the vpn_vpn, which is not desired for me.
I had tried to use the "route del default gw 0.0.0.0 dev enp5s0f2" command to delete the default gateway. It works when I configure the enp5s0f2 manually (ifconfig enp5s0f2 up, dhcpcd .. etc). However, when the NetworkManager tool is enabled, the route table didn't see any change no matter how many times I type the command... |
