xfinity xb3 router port forwarding

[freakaftr8]

Hey guys so I switched up to this new Xfinity xb3 router although it seems nice and it's replacing my failing Asus 5g all my internet ports or at least my addresses are all 10.0.0. Something. All of this didn't bother me too much I can't figure out how to get into the router to address port forwarding so I can make my Synology DiskStation read in the house for plex Media Server. My Smart TVs are saying that they cannot connect to it anymore. Now does this have something to do with me and static or dynamic? And how the heck do I get into the router to address port forwarding rules? I can't seem to find any information on the IP address to get into the router. And people that say they have have had nothing but problems with port forwarding but I can't seem to find information on how to get in to start.

I've the XB3 (DPC3939) and it's complete crap. Beware that for port forwarding you WILL need to restart in order to view what you've just done or to fix\disable anything. For whatever reason it likes to quit displaying anything there after a day or so. I ended up shoving the thing into bridgemode and it hasn't given any trouble since.

The address for mine was 192.168.2.1 from the factory. One way to find what yours is running on is to run an ipconfig (or ifconfig) and see what the gateway is set at.

Example:
Wireless LAN adapter Wireless Network Connection 2:

Connection-specific DNS Suffix . : hsd1.ca.comcast.net.
Link-local IPv6 Address . . . . . : fe80::34b8:610f:361:b95b%16
IPv4 Address. . . . . . . . . . . : 192.168.2.101
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.2.1 <-- This would be the address for the modem

Unfortunately I can't check at the moment but I believe there's a sticker on the bottom that'll have a user\password. If not there on the back.

Thanks again for the help..the sticker that has the login password for the wifi won't do. I'm thinking of calling comcast. This things lame
