Small Business Frontier Fiber with Failover Cradlepoint LTE ISP
Like the title states, could anyone please help me with your experience regarding implementation / troubleshooting?
I have a small mom pop shop that has maybe 10 wired end-points going to a regular switch then after to a TP Link ER600 with failover setup on LAN2. I have the ONT connected to WAN on the TPLINK Router, and a single cable going from LAN2 ( fail-over ) port going to a port on the switch on Cradlepoint, but I am not able to view all websites.
As a test, I disconnected the Cradlepoint from the network, and connected a laptop to a port on the built-in 4 port switch, I am not able to access HTTPS and CDN sites, not even Facebook as a test, but Google pops right up, and this is using the LTE connection only, completely disjoined from the network just power, and one ethernet connected. MTU issue? I know Frontier manages it.
No static IP is in use on Fiber line. FYI
Could I request to set to IP Passthrough / Bridge mode? Disable its NAT? What about content filtering? Does Frontier maintain a firewall or some sort of content filter? It seems only lightweight websites load. The client is not running any extra services like RDP VPN SMTP etc...
Please help if you can... MUCH thanks in advance for any kind of help!
