Hello Rafael, Thank you for your reply. The key problem in my case is that I'm using a complex NAT/Mangle setup, with too many decisions to be made. When I finally succeeded, I was able to pin-point the glitch in my setup: "Ensure NAT Rule is Applied to WAN Interface Only" in your excellent guide. Since I'm unable to do that in my setup, I used a better and more safe approach: just create a nat rule that will ACCEPT traffic from intercepted clients with no further action, and place it well enough higher in the nat rule-chain so it basically skips regular nat. Thank you for the excellent guide.
