I have ZTE 5G modem with MT behind it. Have been using this set-up in bridge/passthrough mode where the modem hands over the public IP to MT (have real one, if this matters) for more than an year and everything was fine & dandy until last weekend when there was storm (doubt it’s connected).
Now the combo works again, but only if the modem is in firewall mode. In bridge mode, the MT doesn’t get assigned the WAN IP and traffic is dead. The modem however can ping, etc.
Could it be something I’ve changed on MT side?
