EDIT: fixed. The problem was unrelated to MT CCR. The link is buggy and traffic was routed through another paths. Deleting this thread is up to forum admins.
I'm experiencing very strange problem: I have NAT for customers and I can't reach more than 2mbit/s when downloading from internet . When Fetching witch /tool fetch from internet I get my link saturated, more than 60mbit/s.
But when I upload, I can also saturate the link.
I have checked everything (?). I have also other things (hotspot, firewall, vlans, sstp) so I disabled what I could, removed every queue but nothing worked. I rebooted the router but all remains the same.
I'm despair to fix this - what shall I do next? is it a known bug or what?
EDIT: I have also run bandwith test from the position of customer to CCR - it runs fine, 100M/100M runs OK. So it seems like only NAT is somehow wrong, but I can't really tell why... Meanwhile, I have upgraded from 6.2 to 6.4.
