Hi all,
I am trying to set up a gateway to communicate SIP clients as this:
Client A Client B
Private IP <---------- Gateway ----------> Public IP
Due to some requirements, it is necessary that the gateway makes
masquerade which provokes problems when the communication is set up
(RTP streams), because Client B try to send the messages to a private
IP.
I have read that the module ip_conntrack_nat solves the problem... but
I tried several times and it has been impossible to install it. I
tried also with nf_conntrack_sip and nf_nat_sip with the same result.
The Gateway is running Ubuntu 9.10 with 2.6.31 kernel.
Please, can you tell me which patches I have to install for the
gateway to support NAT of the data streams and also how to install
them or a link with this information?
Does the module conntrack-tools incorporate them?
Thanks in advance,
Rebeca Martinez
