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
- Default Username:
- Default 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:

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.
