Voip : Only one way speech is working between 2 Sites!
-
i created this rules but no résult
source (ports) => destination (ports)
adresse PBX site A : 172.16.1.200 (UDP 32000-32512 ) => adresse PBX Site B 172.16.2.200 (UDP 32000-32512)
-
Create one with serverA => serverB and serverB => serverA.
Free all traffic between voip servers.

i did it !! no résult >:(
-
I think the problème is in the NAT !! because when i turn off NAT filtre in advance setup the voip work very good, but the navigation in internet don't work (no internet acces) so i don't know how to give acces to internet !!! do you have any idea ????
-
The server is on the same subnet as machines?
If so, disable automatic nat and create your own nat out rules.
Ps.
It sounds strange to me that some services will need nat and some don't. -

I really don't understand this problème!!!
i tired every thing to resolve it but no solution until now!!now i'm trying to make the VOIP work just between 2 sites but the firewall still block the voip!
the ping between 2 sites A and B is good also the transfer of DATA from A => B and B => A!
Site A :172.16.1.0
ALCATEL PBX A : 172.16.1.200
Site B :172.16.2.0
ALCATEL PBX B : 172.16.2.200i created those rules,
in Server A :
Rule 1 :
Lan Interface :
Action : Pass
Interface : LAN
Protocol : Any
Source : Lan subnet
Destination : Single Hoste Or Aliace (Site B)
Geteway : default
Rule 2 :
Lan Interface :
Action : Pass
Interface : LAN
Protocol : TCP/UDP
Source : Single Hoste Or Aliace (172.16.1.200)
Port : from 32000 to 32512
Destination : Single Hoste Or Aliace (172.16.2.200)
Port : from 32000 to 32512
Geteway : default
–-----------------------------------------------------------
in Server B :
Rule 1 :
Lan Interface :
Action : Pass
Interface : LAN
Protocol : Any
Source : Lan subnet

Rule 2 :

–------------------------------------------------------------
Alcatel support say that the VOIP need just port from 32000 to 32512 but i also tried to autorise all port!! but no résult!
in Diagnostics: System logs: Firewall : the firewall still block the voip !!!

Do you have any idea? ???
-
Have you disabled nat between sites?
Use tcpdump at console and see packages flowing
-
I turned off the NAT in advance setup, it work good ! but users can't have the internet navigation!!
how can i block the nat just between the 2 sites ???
-
With manual outbound nat, there is two ways to do it.
either you have rules to these networks with a check box: DO NOt NAT and after that destination any network with normal natting-or-
almost similar, but any other destinations has to have nat rule except these 2sites.
-
It's probably not NATing between the sites, it wouldn't by default at least, you would have to setup manual outbound NAT for that.
