Then it's just like the devices are on that LAN so only your newest networker would thing this is any protection for the devices.
In short, the password for the router is fine but it's not a router at this point as it's in bridge mode.
I'd take care in my words since you have a bridge, not a router according to your post.
Please advise me how to secure my router in bridge mode.
I plugged my cisco linksys router to a public shared network. I would like to isolate my router and protect all the connected devices.
The router already has a strong password, it is enough?
