- since nobody has answered this one so far -- as far as i know vxworks does
- not forward broadcast ip packets. grab a copy of ip_input.c from 4.3
- bsd tahoe release, which is essentially used unchanged in vxworks 5.0 --
- and read it. the ip_forward() is *not* called for the broadcast packets.
-
- possible source of error: either interface is not configured correctly
- with proper broadcast address which matches the net/subnet mask, or a
- problem with the driver itself -- not likely.
-
- i'd like to find out more about various configurations, details, etc.
