Dear Daniel.

 

Thanks for your quick reply and fix.

 

The proper solution for us is to make the backend stop sending keepalives as they are not needed in this case. I’ve asked our supplier about this as I couldn’t find an option for it. I’m assuming that the backend incorrectly detects NAT and then automatically sends these packets.

 

I’m not a C programmer, but the fix looks good to me.

 

With kind regards
