My setup is: one FreBSD server, one interface, two ISP, each providing
a router. So I would like to set up a dual homed host, to be able use
the two ISP. From some reading of the FreeBSD documentation and
gooooooooooogle, here are my questions:
0) do I need to do a sysctl net.inet.ip.forwarding=1 to get a working
dual homed host ?
1) I set an alias (private IP to use the ISP2): "ifconfig rl0 inet
10.0.1.4 netmask 255.255.255.0 alias", the I can ping 10.0.1.4 but not
the router at 10.0.1.1. What's wrong ?
2) I set route: "route add -net 10.0.1/24 10.0.1.1 0", but yet I am
still not able to ping the router at 10.0.1.1 or to ping my public IP
from another network.
If I set the defaultrouter=10.0.1.1 (ISP2 router on my network) in
rc.conf I can use the ISP2 public IP to acces my server, but then I
loose the access to the primary IP of the ISP1...
Thanks a lot for your help.
