My Solution was to hit SAVE again under Interface configuration.

Maybe there is an MTU size problem or a Speed negotiation problem with that interface and the fiber modems?

Thanks for the reply! However, I've been using these same modems with the same ISP for the past 1 year. This issue has suddenly popped up out of the blue.

Can you show us the non-functional interface definitions?

OK, did you restart or unplug these modems from power recently?

Was there an update on the firewall system?

Why is one port on "Automatic" while the other is at "1000 Mbps - Full duplex"?

I would try setting MTU to 1300 bytes for one of these ports and then watch the reaction of that uplink.

If that helps, try the other port with that same setting.
