Port 3671 is blocked from any public IP address

[domotiqa]

Hello,
I used to have remote program on demand for my customer. I press a button wich open 3671 port temporely, then program, then push off the buton with a script. I also have a script wich close it at 24h00 just in case of forgot.

My Problem, is that, since 2.6.1 firmware on SL/HL, they put security update:

security: disallow KNX/IP Tunneling connections from external IPs (Port 3671 is blocked from any public IP address)

I did'nt understand why it was'nt working anymore, but it was the explanation.

My question, is there a way to allow it, or at least allow my office IP ...


ANy help, would be precious.
Best regards
