Port forwarding does not work

Region : Italy
Model : TD-W8961ND
Hardware Version : V3
Firmware Version : 3.0.0 Build 120720 Rel.09287
ISP : alice
A couple of weeks ago I have bought a TD-W8961ND in replacement of my old modem/router (of another brand, to upgrade from Wireless G to N).
I tried to replicate in the new router something similar to my old setup, so I programmed Virtual Servers (under the NAT menu) with the following rules:
in an attempt to:
- grant access from "outside" Internet to my web server
- have a Wakeup-On-LAN from "outside" Internet
..etc..
without success.
Please note that:
- I have successfully setup a DDNS server to reach my modem router from outside
- as for WOL, I defined my subnet mask as 255.255.255.128
- I have not set any other rule, nor in NAT, nor in routing or other
- I tried also with firewall disabled
- I do my testing by means of a smartphone with wireless disabled and Internet connection via mobile service provider
- Both the above mentioned functions were working with my old modem/router (and still work on LAN), and I have not changed other things (PC setup etc)
Please, please, HELP !

Yes! In LAN both WoL and web server are working now... (and were working also from outside with my old modem/router)

In this configuration 192.168.1.127 is a broadcasting address in your network. You have to make forwarding on computer IP.

I know this is a broadcasting address (for this purpose I have choosen the 255.255.255.128 subnet mask).
Forwarding on specific IP could work only if the PC was already ON (but is not working for me: note that even the web server does not work, with correct IP forwarded and statically defined in the PC software, and choosen outside the DHCP area). For WoL I think is necessary to resort to broadcast, otherwise the router may refuse to forward the packet on LAN.
I do not think my problems are specific to WoL.
As for web server I have tried also with PC configured to get the IP from the router's DHCP server (configured to statically assign the choosen IP to the PC's MAC address)

For WoL very important is ARP Table where your mac address must be type in. Normally this mac address is ejected from this list after a few minutes after off your computer.
I can't understand what is wrong with your web server please explain again.

OK, for web server:
On my LAN I have a PC, connected by WIRED LAN to the modem/router, which run a web server (Apache). I switch on the PC manually, wait for completion of system start-up and then test the web server.
I test it on wired or wireless LAN with another PC and wireless with my smartphone (with wireless enabled): it works.
I test it from the "outside internet" (my smartphone with wireless disabled and internet access from my mobile provider): it does NOT work.
---
As for WoL.
The same PC on which I have the web server is now initially OFF. The situation is similar: it works from inside, does not work from outside.
---
Therefore I think that the router does not do port forwarding. I repeat: with my old modem everything used to work fine (and still works, if I replace it back).
---
By the way, I thank you for your attention

web server: yes, 192.168.1.100 is the local address.
My old router was a Dlink 2640R
I will study the ARP table/telnet solution, but IMHO, the ARP table has relevance for all the LAN trafic, therefore, regardless of the origin of the IP packets, the behavior should be the same, shouldn't it? But in fact I have different behavior on LAN and WAN.

If you like give me your public Ip address on Private box (PW) I can check your web access on my computer.

It was my last idea to solve your problem ;)
