Well, there are some furtive ways of starting it, assuming it's not closed with the alarm which forbids the starter engine to work
And the error message, I'm saying he never left me on the way (about my father the conversation is different ^^ )
And about the port... I don't know, I've tryed the technical assistance of my ISP, they came to my home because of an issue and I've tryed some config on it. But like I said, it doesn't work with the modem, with the router, so I'm assuming it's not ISP fault, it worked before, they didn't change anything or any rules on internet access, without firewalls blocking I really don't know what to do here :/
Oh, and I also reached Panda assistance they explained when firewall is disabled, the truprevent technology (protects agains unknown attacks) might be locking a specific program if any info that bypass panda look suspicious (bla bla I don't know if it is that way but I belive it so lol)... But by adding a free pass to the LFS ( he can use any door for in and out ) that will be enough so Panda will not be the problem. They recomended to do the same on windows firewall: add an exception even if I don't use it... [I don't use it because they may conflict one with the other]. They were very nice, as well as you are being, trying to help solving this but... It looks like it don't want to be solved...
