I'm on OSX Yosemite and I have two different active connections... - WIFI (en0) - Tethering USB (en7)
SnakeBook:~ root# netstat -nr
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 192.168.1.1 UGSc 14 4 en0
default 192.168.42.129 UGScI 0 0 en7
Now...I need to add a route to browse some websites by tethering connection. For example, I want to run a speedtest on speedtest.net using en7. Speedtest is resolved this way by my DNS (192.168.1.1 that use OpenDNS)...
SnakeBook:~ root# nslookup speedtest.net
Server: 192.168.1.1
Address: 192.168.1.1#53
Non-authoritative answer:
Name: speedtest.net
Address: 216.146.46.10
Name: speedtest.net
Address: 216.146.46.11
Now...I added two routes:
SnakeBook:~ root# route add -host 216.146.46.10 192.168.42.129
add host 216.146.46.10: gateway 192.168.42.129
SnakeBook:~ root# route add -host 216.146.46.11 192.168.42.129
add host 216.146.46.11: gateway 192.168.42.129
SnakeBook:~ root# netstat -nr

and trying a traceroute on speedtest.net it seems works fine.
SnakeBook:~ root# traceroute speedtest.net

The problem is when I use my browser. Using browser, traffic always passes through en0 gw and not en7 gw. Is this problem caused by "two" default gateways ?
I tried to remove en7 gw, but It always deletes my en0 gw:
SnakeBook:tmp root# netstat -nr | grep default
default 192.168.1.1 UGSc 30 4 en0
default 192.168.42.129 UGScI 0 0 en7
SnakeBook:tmp root#
SnakeBook:tmp root#
SnakeBook:tmp root# route delete default 192.168.42.129
delete net default: gateway 192.168.42.129
SnakeBook:tmp root#
SnakeBook:tmp root#
SnakeBook:tmp root# netstat -nr | grep default
default 192.168.42.129 UGScI 0 0 en7
Any suggestion ?
Thanks!
