Port Forwarding

I am unable to even look at my ports on my computer and edit, add or delete but I used to be able to. It says that I need to upgrade my brand new modem/router for xFi but it still works on my phone's xFi app. Any help?

Re: Port Forwarding

Yep!!! Same problem here.
So!! I went and bought my own modem ! The ARRIS Surfboard (24x8) Docsis 3.0 Cable Modem Plus AC1750 . Then XFI hijacked that modem also. I couldn’t setup port forwarding on that modem also!!! When I login the port forwarding tab would have a link that takes me to the XFi website, then it would say I need to upgrade my modem??!!!


So...... I returned it. and went with a netgear modem and netgear router! Don’t bother calling customer service (twilight zone ) no one knows what you will be talking about. Just avoid Arris.

This will happen with any brand / model of a combination modem / router gateway device. Using a standalone / straight cable modem and a separate router are the key !

Re: Port Forwarding

Thank you it seems having a seperate modem/ router is the way to go, no more renting this from xfinity!

Re: Port Forwarding

so were you able to do regular port forwarding using the Netgear Modem looking at the cm1200 ?

>

or did you need to buy a router as well  and then use Bridge mode and then use the router to port forward

 

I DO NOT WANT XFINITY CONTROLLING MY PORT FARWARDS not yelling at you

just making it big so Xfinity will read

 

let me know what i need to do

using XB6 rented modem now  but will return and purchace the netgear cable modem cm1200

First. The CM1200 is a plain vanilla / straight cable modem. It does not have a router / WiFi built in. You would need to use a separate router with it.

 

Second. It is a DOCSIS 3.1 capable modem. You would only need a DOCSIS 3.1 modem if you subscribed to their Gigabit speed tier. Otherwise it would just be overpriced overkill.

Re: Port Forwarding

Did not even take that into consideration that i need some sort of router

i have my wireless separate through a grandstream gw7610 and wish to keep it that way

 

the cm1200 price is ok as i am buying it for the docsys 3.1 and so i do not have to buy another for a vary long time

but itf it does not route then i am at a loss

is there something that anyone recomends for the yes 1g speed that i have ?

all my traffic comes in to my Cisco SG300 and goes from there but this is just a managed switch

 

what modem router combo or not for the 1g speeds would anyone recommend ?

Re: Port Forwarding

I have lost ALL of my external access to my home web cams!!! Comcast has changed how the home user provisions PORT FORWARDING in their gateway. When you had access in the modem there was a "user defined" option where you could MANUALLY build your ports. Now you have to use a webapp to open ports IF the modem SEEs all of your "connected" devices. Mine DOES NOT! I have called at least three days and it still does not work! I need tier 3 modem support or a way to access directly into the modem. As of now all 6 of my web cams are dead im the water!

Re: Port Forwarding

do youself a favor and turn your Xfinity in to a bridge mode and get your self a grandstreen 7630 for your wifi and a Gwn700 router for your router again grandstream when Xfinity did this i was in the same boat so i returned there modem and bought my own grandstream router so so configurable you will love it I am an IT director and love this thing also the grandstream wifi 7630 is great have one on every floor and just perfiect wifi everywhere

if i could drop Xfinity i would but need the speed and no one else has it where i live

also if you need a new modem the motrolla 8600 is about the best that i have found
