Hi,

within a NetBSD installation, I connect to several ISPs via PPPoE using tap 
devices. This works fine, but there's a problem with the routing:

In order to send packets over a certain connection, the socket is being 
bound to the correspondending IP, but that gives me a "no route to host" 
unless I change the default gateway. However, this is no practical solution 
since I want to use all PPPoE sessions simultanously.

Therefore, I have to tell NetBSD that it should route all packets 
originating from the IP of ISP #1 through the gateway of ISP #1 and so on 
(some kind of routing by source address).

There's a how-to for Linux here:

I'd be really glad if someone could describe a working solution for NetBSD 
(using pf, ipf or whatever).

Bye

Daniel
