Well the ifconfig error came from me thinking I edited /etc/hostname.le1
(it still had the same name)

I figured out that I needed to do a:
        ndd -set /dev/ip ip_forwarding 1


Still does not send packets.

I noticed in one of my many sanity reboots that IPF errors saying
something about layer 2 invalid header or something or other. IPF was a
binary install. I think this layer 2 something or other is my issue I
need to concentrate on.

Any suggestions, help, pointers, etc would be awesome.


TIA
