I am using Firmware: DD-WRT v3.0-r35831 std (04/26/18)
My router is the older model with S/N starting with: 198106

Local IP is 10.0.1.1
DHCP starts at 10.0.1.100

The computer I'm trying to forward to has a static IP of 10.0.1.20.

Today I tried to enable port forwarding for the first time. It was simple:

TCP 25565 -> 10.0.1.20:25565

As soon as I apply these settings, all internet drops out. This can be confirmed on the router by trying to go to the speedtest service which displays an error saying that it can't connect to some remote server.

If I disable the port forwarding then everything is fine again.

I can forward the port if I instead use 'Port Range Forwarding' and specify a single port.

Can anyone else confirm?

Just got WRT3200ACM, and flashed with the 4-26-18 35831, and can confirm happens with this router - as soon as enable a port forwarding, no more internet.

there is a workaround by Banjo

1) Use Port Range Forwarding instead
2) Enter 0.0.0.0/0 in the Source field
