Hi All,

	Does anyone have a positive experience in using real audio proxy on 
Solaris7_x86? Whenever I try to use UDP transport, IPF blocks all 
incoming UDP traffic as I have "block all" rules.

# ./ipnat -lv
List of active MAP/Redirect filters:
map ipdptp0 0.0.0.0/0  -> 0.0.0.0/32  proxy port 7070 raudio/tcp
        ifp e154e9e8 space 254 nextip 0.0.0.0 pnext 0 flags 0 use 2

List of active sessions:

        age 1175 use 0 sumd 0 pr 6 bkt 0 flags 201 bytes 0 pkts 0 0

And this is what gets blocked:

Does anybody have any comments?

Sincerely,
Dmitri
