This could be because Blocked returns 127.0.0.1 as address.

Nigel, there is something wrong with your firewall or router.  Tell your

technician to capture your packets (by starting wireshark for ex.) on

your NAT machine and see where packets are lost.  This is the surest

method to see what happens.

Dear Eugen/Ekiga members,

 

I have made some research into this situation, just to help myself as this is not an area with which I am familiar.

Our IT Technicians will not assist further, they have opened the ports to my machine 192.168.10.27. SIP communication is not high on their list of priorities, they are willing to let me use Skype but here in Tunisia that’s a disaster. I can confirm all ports have been opened. I can confirm I am behind a SYMMETRIC NAT, (so STUN is not relevant?). From what I can see, my pc will send a request to the Ekiga.net or Iptel.org servers (I tried another account) but can not receive the response. I can confirm by looking at the dump, that my pc sends its own private IP address 192.168.10.27, not the public one, from our ISP, 193.95.76.165. I read on a VOLP user forum that the SIP server must send the response back using exactly the same IP address/port combination - could this be the problem?

 

Local IP: 192.168.10.27

Public IP: 193.95.76.165

DHCP Server:  192.168.10.3

DNS Server: 192.168.10.3

Default Gateway: 192.168.10.254

 

Regards

 

Nigel Brown
