Enable 3671 KNX IP port for maintenance

[domotiqa]

I was thinking about an idea 

Is it possible to enable the IP port 3671 with an icon on the visualisation.
For example, we port forward (without VPN) the 3671 port trhough Internet, but the customer can enable it/ disable it only when we needed maintenance !

Should be cool and "safe" (because it don't stay too much time enable, maybe watchdog...)

Hi,

Why don't you use a IP based forwarding instead of a 0.0.0.0 ?

This way only connections from that location are accepted.

Safest way and you can keep the port open if needed.

Yes you'r wright, however, every internet box doesn't allow this.
In my exemple, the suctomer has the feeleing to control when I can access, and it's more flexible.

Do you know if it's possible ?

@ Admin: Is iptables included in the system?

You can enable/disable KNX/IP via event script:

Code:

enabled = event.getvalue() and 1 or 0
uci.set('eibd.@eibd[0].knxip=' .. enabled)
uci.commit('eibd')
os.execute('/etc/init.d/eibd restart')

Ok thanks for this great help.

Just a doubt, it will stop KNX communication during few second right also on TP side ?

Yes, but the loss is much shorter compared to reboot
