Add Ubuntu information how to open firewall for Xdebug

No description provided.

This is flavor specific, also people tend to choose their own firewall(ufw/iptables/shorewall/etc).
I know I've enabled this ufw firewall on your pc, otherwise it would had been turned off by default :)

Maybe we could have a section in the wiki on this.

As I spoke with @JeroenBoersma earlier today, I mentioned revamping the README for this repo. I'd be happy to include said instructions in it, if you provide them for me.

[Caroga]

Any update on this matter? I found some time to do the docu rewrite this week, so if you wish to include this than copy the ubuntu specific configuration in here and I will make sure to address this in the new docu.

[JeroenBoersma]

For Ubuntu it'll be; (I'll prefer command line because I don't want to describe every graphical configuration tool)

sudo ufw enable # if you didn't already, shame on you
sudo ufw allow in on docker0 from 172.17.0.0/24 to 172.17.0.1/32 port 9000 comment xdebug

[Caroga]

Ofcourse. Also, I believe that UFW is enabled by default? I could also add the native iptables equivalent if needed?

[JeroenBoersma]

Believe again; ufw is disabled on clean installs!

[JeroenBoersma]

maybe iptables is a nice addition

[Caroga]

Okay, I just see that my first_boot script enables it, therefore the wrong believes ^^,

[JeroenBoersma]

@Caroga are you still willing to add this info?

[JeroenBoersma]

Start with ufw and we accept PR's on all others

[Caroga]

@JeroenBoersma yes, I will create a PR to collect all additional info and update the documentation.

this works for me:

sudo ufw allow in from 172.16.0.0/12 to any port 9000 comment xdebug
