Read up on the "writing rules" Snort docs [0] -- Snort is rather specific in
its format for rule writing.

Would it be possible to use 'pass is <address> any -> <address> 
<PROTOCOL>' ?
I would like not to log traffic originated from specific host only on 
specific protocol....
Thanks you.

10.0.0.0 is not a valid host IP -- it's a network address.  So if you 
want to have the 10.0.0.0 network be the destination of the pass rule, 
then the rule should look something like: 

        pass ip 10.0.30.4 any -> 10.0.0.0/8 any

The second rule should also include a port designator: 

        pass ip 10.0.20.6 any -> any any

See if this helps.

I have 2 pass rules that I placed in local.rules: (snort started with -o)
pass ip 10.0.30.4 any -> 10.0.0.0 any
pass ip 10.0.20.6 any -> any
First should take care of cluster servers broadcasts, second takes care
of weird ICMP redirects from Shiva device. Snort cannot be started and
it complains about those pass rules, the moment I disable 'em snort is
started and it works fine.
Is there a syntax problem with those pass rules?
Thanks.
