Comcast Xfinity Camera Issue Solved Without Port Forwarding

I was able to get cameras and doorbell working out setting up port forwarding with the Xfitnity router listed below:

Comcast Xfinity Router Details:

- Router  Hardware Details:
  -  Model: TG1682G
  -  Vendor: ARRIS Group, Inc.
  -  Hardware Revision: 12.0

- Router Software Details:
  - eMTA & DOCSIS Software Version: 10.1.27B.SIP.PC20.CT
  - Software Image Name: TG1682_3.14p8s1_PROD_sey
  - Advanced Services: TG1682G
  - Packet Cable: 2.0

It appears that multicast needs to be enabled for the cameras to work.

This not ideal but I wasn't having luck with port forwarding.

This may cause issues with certain applications and devices and it is not as secure as having the router security set at maximum.

Steps:

1. Logon to router   http://10.0.0.1/
   - Default Username: admin
   - Default Password: password

2. Navigate to IPV4 Firewall Setting
   - Click Gateway->Firewall->IPV4

3. Select Custom Security

4. In the WAN-to-LAN : IDS Enabled and block as per selections below section
   
  Check the following:
  Block http (TCP port 80, 443)
  Block ICMP
  Block Peer-to-peer applications
  Block IDENT (port 113)

  Uncheck:
  Block Multicast
  Disable entire firewall

This seems to have resolved the issue. I was on Low Security, which should allow everything described in the customer settings here, but I changed it to custom. Seems to be working.

I have only had a single disconnect so far and it seemed to be one camera needing a reboot.

I just found this. I am having issues with random cameras dropping. Hoping this fixes it. Thank you.

Thank you so much for this.  I too was on low security but since changing these settings the live feed on the app instantly switches between cameras.  Not like the 3-5 second lag I used to have or a dropped connection.

My outdoor cameras would only work with the firewall disabled. I tried the above recommendation and the cameras would not connect.
