ObiTalk - Portforwarding

RouterOS Beginner Basics
1

Can you please help me figure out why this isn’t working?

I had to get a Mikrotik router for comcast fiber. I’ve got a lot to learn and can really use the help.

From Obitalk:

What ports should I keep open on my router/firewall?
In order for your OBi to be able to send packets w/o interruption, please configure your router as follows:

Allow Outgoing:
TCP Ports: 6800, 5222, 5223
UDP Ports: 5060, 5061, 10000 to 11000, 16600 to 16998, 19305
Allow Incoming on UDP Port: 10000

My internet comes in on sfp-sfpplus1
I have a bridge on all the ports for my internal network (router).

add action=masquerade chain=srcnat out-interface=sfp-sfpplus1
add action=dst-nat chain=dstnat dst-port=32400 in-interface=sfp-sfpplus1
protocol=tcp to-addresses=192.168.1.103 to-ports=32400

FWIW … I have 3 Obi’s and they work with no special configuration whatsoever. Inbound and outbound calling. Have you tried it with just the default MikroTik NAT/FW configuration?

Also … “Allow” should not be interpreted to mean Port Forwarding. It is pretty rare these days to have to configure port forwarding for client VoIP devices. The connection for the SIP signaling and the RTP voice packet stream is always initiated by the client device. So, inbound is just normal return traffic.

I can make outgoing calls but the phone will not ring when people call the number.

Did you do anything to make it work?

4

Nothing special, pure “plug-n-play”. No specific NAT or FW rules. All those src-nat and dst-nat rules should not be required.

5

Does it matter that I’m using google voice on the ObiTalk?

Fixed it. You were correct, I didn’t need the forwarding. Had to check the “Forward calls to Google chat.” Not sure why.

Thanks for the help!
