Hi,

I have installed a firewall without nat, it deny some networks and permit
some other networks, very simple.
All works fine.

For control it, I have installed vnc with help of this article
http://forums.fedoraforum.org/archive/index.php/t-1606.html
and work fine if I don't up the firewall rules...

If enable firewall rules get in the log always this registration:

Jul 25 22:50:50 localhost kernel: RULE 0 -- ACCEPT IN= OUT=lo SRC=127.0.0.1
DST=127.0.0.1 LEN=35 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=32797
DPT=177 LEN=15

Jul 25 22:50:50 localhost kernel: RULE 3 -- DENY IN=lo OUT=
MAC=00:00:00:00:00:00:00:00:00­:00:00:00:08:00 SRC=127.0.0.1 DST=127.0.0.1
LEN=35 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=32797 DPT=177 LEN=15

and vnc from remote appear like a black screen... if I reset iptables all
return to work fine...

I have try to set all rules to 'allow' but don't work...

Somebody have some hints?
