I'm developing an application to set the interface to use for different
IP addresses, e.g. if I want to use a modem to talk to certain
"protected" nets while using the ordinary ethernet port for web access
a.s.o.
I've wracked my head for two days now, trying different ways of making
"route" do the job, to no avail. At the moment I'm running with the
ethernet card (en0) as 192.168.0.2 and a wlan card (en1) as
192.168.0.5. Now, I want to reach the address 192.168.0.3 through en1
instead of en0. If I try i.e.
route -n add -host 192.168.0.3 -interface 192.168.0.5
no traffic at all gets through, and I have to delete the route again.
Netstat -r gives me (no change after adding the above route):
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif

default UGSc 13 137 en0
localhost localhost UH 12 56901 lo0
169.254 link#4 UCS 0 0 en0
192.168.0 link#4 UCS 2 0 en0
0:5:5d:dc:33:3c UHLW 13 0 en0
765
localhost UHS 0 47 lo0
0:50:e4:30:7a:71 UHLW 0 54 en0
324
localhost UHS 0 0 lo0
I've only tried this in Windows before, so please bear with me if I
seem like a total newbie!
Thanks for any help!
