我想通过openvpn (tun0)通过特定域的stream量，其余通过eth0如何configurationopenvpn使用eth0？
使用ddclient设置域名来更新dynamicDNS。 但我使用tcpdump进行检查，并且不会从tun0中捕获请求
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
我试过了：
ifconfig eth0:1 xxx131 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:xxx131 PtP:xxx131 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)
