SIP Not Working Behind Pfsense

[Janiboy]

Thanks for the replies,

Sorry the provider wont give any details, because they don't want to loss their profit on the cisco router because every month we are billed.

i only have the IP on that cisco firewall.
IG0 - 10.200.94.182 /30 going to their modem
IG1 - 192.168.1.1/24

but i will try ask them again if they can provide it thanks.

but i dont know how to Set static mapping in Pfsense .

I have several pfSense implementations with VOIP phones and other SIP devices behind. Generally these days most VOIP providers do not need static port but there are one or two that do.

@janiboy

Go to /firewall_nat_out.php ( http://"yourfirewall"/firewall_nat_out.php )

or another way to describe..

Firewall / NAT / Outbound

... Ill get a screen capture momentarily..

[chpalmer]

Go down to mappings and then "add"..

[chpalmer]

The local address shown would be my SIP device/client machine. If it is a machine doing multiple tasks then adding the SIP port would be prudent.

[chpalmer]

"Outbound NAT Mode" then should be "Hybrid".

@derelict Talked to SIP provider, They know about the config maybe non technical person, by the way sip cisco router model is Cisco 4321.

You need to add your client device as the "source".

Please note that even if your "Wan is 10.200.94.182" , that is not your public ip address (aka the ip address you are seen with on the internet).

Somewhere between your "Wan" and the internet someone is Natting your 10.200.94.182 , to a non RFC1918 ip address.

You could (from a browser behind your WAN) , go to this site : https://www.myip.com/

And it will show what IP you currently are seen as on the internet.

That would also be the ip address that external sip devices (phones/servers) should reply to.
