Efficient EN5861 firewall

[glocal]

I managed to configure my Efficient EN5861 to forward port 10001 properly, I get the green light and uTorrent's port scan returns OK but I can't get it to work with my router firewall. The moment I turn it on uTorrent's traffic drops to 0, the moment I turn it off, traffic is back to normal. So it must be the router firewall. The green light remains green either way. The relevant lines are:

remote ipfilter append input accept -p tcp -sp 10001 internet

remote ipfilter append output accept -p tcp -dp 10001 internet

These should work, but they don't so I added:

remote ipfilter append input accept -tcp syn -dp 10001 internet

remote ipfilter append input accept -tcp rst -dp 10001 internet

remote ipfilter append output accept -tcp syn -tcp ack -sp 10001 internet

remote ipfilter append output accept -tcp rst -sp 10001 internet

No luck. Anyone with Efficient EN5861 experience? Or anyone who can guess what is going on here? I checked the FAQs and spent hours trying different combinations but nothing happens.

Thanks
