Multicast connection is accepted although currently used TTL value is 1 and originator is located in another subnet

The device does not reject a forward open request opening a multicast (T2O) connection to another subnet in case the TTL value is set to >1 but has not yet been applied.

When the TTL value is set to greater than 1, the device sets the configuration pending bit to signal that the device needs a reset in order to apply this new TTL value. In that state where the device has not yet applied that new value, it shall reject an incoming forward open with status 0x813 in case it want to open a multicast connection to an originator that is located in another subnet.
