I'm trying to add devices to the dude 4.3 that need to be accessed with ports
ie x.x.x.x:8290
the port forwards in our router work fine but when I add the device's dude is not happy having a port associated to the IP address and clears the input and sets it back to all 0's.
Is there any way to do this?

Thanks

I would try creating the device just using the IP address, then set up a probe that is configured for the particular port that the device has open. DNS, TCP and UDP probe types can have ports specified.
