i'm on a multihomed FreeBSD 4.9-RELEASE, cvsupped and built to -STABLE as
of two weeks ago. the two NICs on the box each go to different ADSL
providers. right now, i can switch which provider i use by just manually
changing the default route. however, what i'd like to do is to have the
default route set to one provider, but manually add static routes to
networks closer to the second provider going out that way.
EXAMPLE OUTPUT OF NETSTAT -RN:
default 192.168.0.1 UGSc 13 2878 fxp0
10.1/16 link#9 UC 2 0 aue0
10.1.105.5 00:e0:7d:03:a2:08 UHLW 0 363 aue0 815
10.1.105.26 00:08:54:d0:5d:2e UHLW 1 0 lo0
60.6/16 10.1.1.1 UGSc 0 0 aue0
127.0.0.1 127.0.0.1 UH 0 12407 lo0
192.168.0 link#2 UC 1 0 fxp0
192.168.0.1 00:30:ab:10:6c:0d UHLW 13 215 fxp0 913
(192.168.0.1 is ISP1's router and 10.1.1.1 is ISP2's router)
i've successfully managed to add routes for /16 networks, and 'netstat
-rn' as well as 'route -n get' both give the expected results. however,
tracerouting to an ip address in one of these static routes still shows
that it is going out thru the default route instead of the second
provider. running a packet sniffer and attempting a http connection
confirmed this. in this case, any packet going to 184.108.40.206
what exactly should i be doing to get the behaviour i desire ?
a secondary question is, with the /usr/ports/net/zebra package, can i
configure this box to load balance flows over both ADSL connections,
assuming i do not have an AS number (for BGP) handy ? i.e. the question
is, assuming i make a tcp connection out using a browser (for argument's
sake, mozilla), can mozilla send the packet out dynamically on the first
NIC (with its IP address as source) and then round robin the next TCP
connection off the second NIC (with the second IP address as source) ?
would i need the recent multipath patches (though its for 4.8-STABLE) to
do this ?
