Hi,
Hope someone can help me. I have a fairly bad NAT situation.
Clients are behind NAT and SER is behind NAT. The idea is that the clients will register to the public address which is assigned to my router and I have enable port-forwarding to send the packets onto the pc running SER listening on 5060. This situation worked when clients registered with Asterisk but I would rather them to register with SER and just use Asterisk for voicemail etc.
My config is like the default except the nathelper and mysql modules are loaded. I have looked at the following websites but all the configs are very different and use different rtp proxys..I am also confused as to how much configuration is required to accommodate nat

Could someone give me an idea of how the script should be modified, what else must be installed (rtp proxy wise)or any ideas as to why my clients cant register?....Im presuming its nat...
Thanks a million, Aisling.

I'm in the same bad situation, but I managed to make voice work. I'm using nathelper+rtpproxy. What made things work however is a patch for rtpproxy cvs Greger Teigre posted on the list as attachmentent in november (I reposted it on 1-17-2005 as text of message as attachments are removed in mailing list web archives). I wrote nathelper part of ser.cfg copying directly from nathelper module examples, just don't forget on_reply_route. Add your public IP and domain as 'alias' in the top of ser.cfg (on 'listen' put private IP), and if you use 'domain' module add them in mysql tables.
now I'm working on sems integration, if you think you will use it, let me know if you manage to make it work
