What tutorial exactly?
Can you please share your config (/export hide-sensitive file=anynameyoulike) and remove all personal information?
I'll try and find it but there was a number of them i came across.
this is the export. hopefully its right. I've change my external IP address to my-external-ip on the export
the isp_1 is my static IP and the isp_2 is dhcp from the ISP. it was meant as a backup line but as the line only gives 72mb max i tried the dual wan. but not sure if this has affected port forwarding
