Hai Mr. Stuart Henderson,

Thanks for the hint on -mpath.

I am just trying to get the internal to external. I had two ISP, and
when I try to route add default at the second time I got
route: writing to routing socket: File exists
add net default: gateway 10.10.10.2: File exists

So I am wondering how do I send out traffic to the ISP if I don't
have routing.

I know that I can use PF to route the internal to external traffic.
I thought that I need routing in order to use PF.

I mean to say that I can't use OpenOSPFD and OpenBGPD.
My mistake. Sorry for the inconvenience. The ISP will not
support it, the only can support static route from us and from
them to us.

Best regards and thanks.
Riwan
