Port forwarding with Comcast
I am putting my Comcast XB7 modem/router in to bridge mode and connecting to an Orbi 370 I am doing this to avoid the Comcast router not doing port forwarding even though I set that up in the Xfi...
It is often helpful when discussing network options to have an idea of:
- What are the goals?
i.e. port forwarding implies a need for remote devices to connect to devices on the LAN. Ports 22 (ssh) and 23 (telnet) are commonly used to connect to a command line interface on a computer.
since each port can be forwarded to a single IP address on the LAN, it would be cumbersome to use port forwarding to allow ssh access to multiple computers. One tactic might be to
o forward port 22 to IP xx.xx.xx.x01 port 22
o forward another port (maybe 222) to IP xx.xx.xx.02 port 22
o forward another port (maybe 233) to IP xx.xx.xx.03 port 22
etc. etc. Obviously, this quickly becomes a nightmare keeping track of which public port goes to port 22 on which computer. - What is the physical wiring layout?
Where are the XB7 modem/router, the Orbi 371 router, the three 370 satellites, the switch, and the vintage computers located?
i.e. what is in the basement and what is "upstairs"?
