The OS is assigning this socket port |and you _don't_ have a way in defining this inside Kannel's config |file. | I had the same limitation so i have emi2 set as a SMSc with this setup:
group = smsc smsc=emi2 host = 10.11.14.13 port = 6611 our-host = 10.22.11.24 our-port = 4982
And all connection goes with src port 4982. a netstat will show
tcp 0 0 10.22.11.24:4790 10.11.14.13:6611 ESTABLISHED
and works fine, except for restarts where i have to wait 1 minuto before the socket will be killed ( but that's more an SO issue than a kannel issue).
|You'll have to go with Linux IP tables and NAT rules to map this. |Unfortunatly I can't drop you an very easy example for this. You |should either patch Kannel's source to define a hard way in connecting |with pre-defined client ports or ask your local Linux guru about the |OS IP layer way in doing this. | You could use inetd to listen to a ip:port ans "send" it to netcat and reset the source ip:port then. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org
