[Asterisk-Users] How to check NAT behaviour before installing Asterisk
Hi, Installing Asterisk involve tuning NAT and network settings. So, before installing an Asterisk server, I would like to check my network settings. My setup is : IP Telephony Provider ----- ISP ------ Home router-firewall ------ Home LAN ------- IPBX and IP Phones What and how would you check your settings ? More precisely, I would like to check outgoing and incoming calls capabilities. What is the safest test to run to be sure that an outgoing RTP flow is not blocked by my firewall (no logs in it) ? Is there some ping-echo-like command I could type-in from a home PC to check, independantly from any Asterisk setting, that a RTP packet would successfully come in ? Ping would be perfect (you can choose IP address and ports and you can access web sites from which you can issue a ping as if you were outside your home network) but, as far as I know, it relies on ICMP which is possibly treated specifically by firewalls. What do you think ? Regards -------------- next part -------------- An HTML attachment was scrubbed...
