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.
