misconfigured sentinel-minipot on 5.0-dev

I'm on Omnia and 5.0-dev. I installed sentinel-minipot. At the end of the installation I try to access from another network to the IP address of the router via telnet, but the connection is immediately rejected. Then I look for a minipot between the active processes and I find this:

root@turris:~# ps -ax | grep minipot
17997 ?        Sl     0:00 /usr/bin/sentinel-minipot -T
18004 ?        S      0:00 /usr/bin/sentinel-minipot -T
21319 pts/0    S+     0:00 grep minipot

We see that no door is indicated. I have seen, looking in the filesystem, that there is in /etc/init.d/ the sentinel-minipot file that manages the service and in /etc/config a file called sentinel, which should handle the minipot port. I tried to make some changes, in the end I decided in the most "raw" solution. I added the default port 2333 to the command line in /etc/init.d/sentinel-minipot. Now I can easily connect via telnet to the IP address assigned to me by the ISP. I think something needs to be fixed in the package installation. I enclose the original and the modified file.
