How to enable rope knocking on-line?

[Makken]

Hi, I'm playing on-line with my friend by Direct TCP/IP and we can't rope knocking. Btw, I have activated in Options, Advanced "enable rope knocking off-line"; but seems that this makes no sense as I thought. What do I have to do to enable hope knocking when I'm playing on-line?

Could anyone help me? I installed the last patch 3.7.2, but before, I was playing 3.7.0 and the same thing happened.

You need to host with ?Scheme=Pf at the end of the game's URL. I haven't tried hosing Direct TCP/IP games myself but I could try and see what happens if needed.
