Is bridge mode really passthru?

Hellohugoleveille​,
Yes, Helix bridge mode is passthru, but it disables routing features like firewall and port forwarding. You must configure these on your own router. To restore FTP access, ensure port 21 is forwarded correctly and your router’s firewall allows external connections. hha exchange

Bridge mode should basically be passthrough, so the Helix itself shouldn’t be blocking your FTP. I’d double-check if it’s really bridged (your router should be getting a public IP) and then look at your router’s port forwarding/firewall rules. Sometimes after switching equipment, the internal IPs change, so the old port forward won’t work until it’s updated. Also, if you’re using passive FTP, make sure the whole passive port range is open, not just port 21. Most likely it’s a config on your router rather than the Helix blocking it.

Yes, in the context of a router or gateway, bridge mode acts as a passthrough, disabling the device's routing, NAT, and Wi-Fi functions so it functions as a simple modem or switch to pass traffic to another router. While some devices use the term "IP passthrough" as an alternative, true bridge mode completely turns the device into a "dumb" modem, allowing a primary router to manage the network and receive the public IP address.

Just to be clear, port fowarding is done and this setup as beend working for years. The only thing that changed is old videotron modem to helix in bridge mode
