Hi guys,
i really need some help with one way audio with h323 protocol.
I've already disabled ip firewall services ports as shown on internet.
I've a CCR as firewall, with this rules.

X.X.X.X public ip
192.168.2.0/23 first LAN
192.168.0.0/23 second LAN

alcatel lucent pbx1 ip: 192.168.1.250
alcatel lucent pbx2 ip: 192.168.2.250
(located in 2 different area, linked by ptp radio)

this is my rules:

\ip firewall nat
add action=src-nat chain=srcnat src-address=192.168.2.0/23 to-addresses=\
X.X.X.X
add action=src-nat chain=srcnat src-address=192.168.0.0/23 to-addresses=\
X.X.X.X

\ip firewall connection ENABLED

\ip address
add address=192.168.1.3/23 comment=Lan_Sede interface=ether3 network=\
192.168.0.0
add address=192.168.2.2/23 comment=Lan_Interna interface=ether2 network=\
192.168.2.0
add address=X.X.X.X/29 interface=ether1 network=X.X.X.Y

all work fine, but when i called from an internal to another i cannot heard him, but him can heard me.
if i call in the same area it's all ok.

if i disable nat rules, i hear all without problem.

I think that the problem is the nat over h323 protocol.

any ideas?

nobody could help me?

Are you using (or can you configure) symmetric RTP ports?
This way audio in and audio out will use same port-pair, so it can traverse statefull firewalls without h323 helper.
