通过 OpenVPN 传递来自特定域的流量

我想让特定域的流量通过openvpn (tun0)，其余的流量通过。eth0 如何配置 openvpn 以与 eth0 一起工作？

使用 ddclient 设置域名以更新动态 DNS。但我使用 tcpdump 检查后发现未从 tun0 捕获请求

tcpdump -vv -i tun0

tcpdump: listening on tun0, link-type RAW (Raw IP), capture size 65535 bytes
^C
0 packets captured
23 packets received by filter
0 packets dropped by kernel

我尝试过的：

ifconfig eth0:1 x.x.x.131 up

ifconfig tun0

tun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  
          inet addr:x.x.x.131  P-t-P:x.x.x.131  Mask:255.255.255.128
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
