SIP Not Working Behind Pfsense

[Derelict]

@bingo600 Yeah, that's why I asked for the config of the cisco and the advice from the SIP provider. They should know every last detail about what NAT, etc needs to happen (ROFL). The advice these days seems to be mostly, "be sure to disable any any SIP ALGs."

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.

Thanks for the reply sir,

@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".

"SIP device/client machine."

The LAN device at 192.168.1.102

@chpalmer no need to add anything ? ok i will give it a try and get back to you thanks @chpalmer

[Janiboy]

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

The LAN device at 192.168.1.102

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.
