192.168.1 My basic hardware setup using two routers
.-----. .-----------. .----------.
.50 | wb |------| lan router|----|isp router|--
`-----' `-----------' `----------'
.-----. | | |
.60 | mtv |--------' | | SIP .-------.
`-----' | `-------| phone |
.-----. | `-------'
.70 | tb |-----------'
`-----'
Nodes using shorewall firewall running Mageia Release 7.1 Linux
Examples are two users on mtv and wb nodes doing the same activity
at the same time on my same internet address/connection.
isp router configured to pass all ports to same ports in lan router.
A simple example, Firefox open a bi-directional connection.
If wb and mtv user run firefox www.yahoo.com and click
Sign In, yahoo only sees my internet ip address.
How does the packet stream get back to the correct user?
A complex example, zoom.us connects 8801, 8802 for the meeting.
I do not know how my router would know to route the incoming
request to the correct user.
The reason I ask, zoom uses these ports,
TCP 80, 443 *.zoom.us
TCP 443, 8801, 8802 MeetingConnector
UDP 3478, 3479, 8801, 8802 MeetingConnector
and if ports 8801, 8802 are the ports zoom.us wants to open for the
meeting. How would the router know to route those packets to the
correct node?
I may be overthinking this. I have a VOIP phone, and I have configured
lan router to forward ports 3478, 3479 to my phone based on the
assumption that the ports are used for incoming phone calls.
