Time Warner Fibre Connection and PFSense
-
Hi Guys
What is the correct way to setup a TWC home fibre connection to a PFSense router. How do I make sure that the public IP address I get on the CPE equipment from TWC will pass the public IP onto the WAN interface for my PFsense box. Does anyone have any examples?
The current setup I have seems to be working but I'm getting issues with SIP/SDP packets getting not making it out the connection to my external SIP provider. The funny thing is that SIP calls can be made to me no problem.
This is the layout
INTERNET <–-> TWC EQUIPMENT <---> (WAN) PFSENSE (LAN)<---> SNOMIPPhone (LAN)
LAN Interface IP is 192.168.16.1
WAN Interface is set to DHCP and gets 192.168.0.5 from the TWC eqipment.
PUBLIC IP from TWC is 98.24.xxx.xxx (I want this to be on the PFSENSE WAN interface)
SNOMIPPhone is 192.168.16.2My SnomIP phone can register and calls can be made to it, just not from it.
I'm suspicious of how the connection between the TWC equipment and the PFSENSE WAN interface is setup. What am I missing?

You need to set the TWC equipment into Bridge mode so the pfSense WAN interface can take control of the dialogue to get an IP address and the pfSense WAN interface into the appropriate mode (probably DHCP). I have no idea if the TWC equipment provides a Bridge mode. If not, you might be able to substitute. Have you tried talking with TWC support?

I've got my problem sorted but it was a little strange.
I was connecting to the SIP server (Switchvox server) via an OPENVPN tunnel. The tunnel was using UDP. I changed it to a TCP tunnel and now I can make inbound and out bound calls over the tunnel.
After doing some packet capture it looked like my UDP SIP/SDP Invite packets being sent by my SIP phone was getting dropped some where so they were never hitting back at the Switchvox PBX while the tunnel was using UDP. As soon as I switched the tunnel to TCP all was good.
I vaguely remember reading something about SIP and UDP in PFsense being a problem, can anyone enlighten me?

The problem was SIP rather than the private IP address on the pfSense WAN interface?

a little off topic, but is this a fiber connection or coax connection? We only run fiber to business class accounts. For ISDN-PRI, Private Network, and straight internet if the speeds need be over 50mps. I would like to it is coax and wallabybob is right that TWC equipment needs to be in bridge mode for you to receive the public IP.

No such problems. Sometimes you have to change NAT settings depending on your provider and your specific circumstances but that's not relevant in this scenario.
The only way changing it from TCP to UDP would make any difference is if the tunnel wasn't functional at all over UDP (something blocking it somewhere most commonly why) and worked with TCP.
