Issues to switch to Xfinity Gateway (Router Changes)

There are several things we need to do to make things easier when change router

1. Use the same network name and password. A lot of devices can automatically connect to the new network as long as the name/password are same.
2. Use the same subnetwork name. In my case, I change “10.0.0” to “192.168.103”. Some hosts may keep the same IPS.

You will run into following issues:

1. IP changes.
   • nuc2-5. The NAS mapping would break when the host IP changes. We need to do
     • umount -f -l /mnt/nas . to force umount the old link. We have to do this other wise even we change fstab file, the new mount won’t work.
     • Change the fstab file to the new ip
     • mount /mnt/nas. (For my case, I need to change /mnt/nas and /mnt/zuora. One to the NAS server and another to my mac mini.
   • Need to change the port forwarding.
2. Public IP changes. This is weired. when I use the Xfinity gateway, the public IP changes to 98.42.113.167. but if I use my own router the ip changes back to 98.37.111.173 . Remap liangqi.org to new public IP.
   

Next time, if I want to change router, most of smart device would just work but I need to:

1. Use the same network name. ip
2. Make sure use the same subnet. 192.168.103.*
3. Check nuc2-5, Nas, MacMINI Ips. If they change, change it in nuc2-5.
4. Port fowarding.

Notes

Limitation on the Xfinity Gateway

1. Port forwarding doesn’t work. I think it may be only 443 and 80. Since the router admin page would use it.
2. Port forwarding has to use the same port in the source and target.
3. Admin page is slow.
4. I switch to use “bridge” mode and then I can use my own router. The thing is now the admin page doesn’t show up and how I can turn off “bridge” mode? Even I don’t think I would try that…

Pending issue

1. need to bind ds220j to 192.168.103.51. If the ip changes, the nuci-5 mapping won’t work (Done. Have to bind the phillip light ip to a different one and then bind again)
