If you want to run rtpproxy to do 4-6 translation you have to use the following syntax:

rtpproxy -f -l private_ipv4addr -6 /public_ipv6addr

(note `/' before IPv6 address)

Check nathelper/examples directory, which provides sample 4to6 config script.

Hi,

I have a problem, when trying to implement a IPv4<->IPv6 gateway with ser 0.8.14 +nathelper+rtpproxy from last version of cvs. (The configuration worked perfectly in an IPv4-IPv4 scenario)

First of all, when I try to make it work with the ipaddr options, the following error occurs;

Gondor:/usr/local/etc/ser# rtpproxy -f -l private_ipv4addr -6 public_ipv6addr

rtpproxy: exactly 1 listen addresses required, 2 provided

Isn't it possible to provide both addresses? Then, the IPv4 address isn't it necessary to specify the Ipv4 address?

Second, when I make teh rtpproxy work only with the -6 option, the rtpproxy works, but then, when I send an Invite and try to establish an RTP session from an IPv4 client to an IPv6 one, the following error occurs:

Gondor:/usr/local/etc/ser# rtpproxy -f -6 public_ipv6addr

rtpproxy: rtpproxy started, pid 19443

rtpproxy: new session 62a81c87fecd3ed8d4da11a57f7eab12@10.100.100.232, tag 28140

81 requested

Segmentation fault

Can anyone give me a clue on what it is happening? The communication just stops after the UA sends the ACK for the 200 OK response.

Can it be due to some errors on internal Unix sockets? If so, how can I identify this error or try to solve it?

Thanks in advance,

Blanca
