>I have a cable provider which provided me these settings:

Since your cable provider assign you an IP in the private
address space you have to uncheck the "Block private networks"
checkbox in Interfaces - WAN in the m0n0 WebGUI.
"When set, this option blocks traffic from IP addresses that
are reserved for private networks as per RFC 1918 (10/8,
172.16/12, 192.168/16) as well as loopback addresses
(127/8). You should generally leave this option turned on, unless
your WAN network lies in such a private address space, too."
