Tom

Confirmed, the patches have fixed both issues.

Note, there seems to be a bug in arptables.

Arprules entry:

DROP  eth0  -  !1

Generates arptables rule:

-A INPUT -i eth0 --opcode ! 1 -j DROP

Issuing arptables-save produces:

-A INPUT -j DROP -i eth0  --opcode 1

The "!" is missing.

I am using arptables v0.0.3.4 supplied with Debian Squeeze.

Steven.
