Mikrotik + free radius : 4GiB download limitation

Good afternoon,

We are using mikrotik to provide internet access with a download quota per user of 5GiB.
However when the user connects, it only shows 1024 MiB instead of 4GiB in hotspot active download limit. (there is the same problem with pptp, pppoe or hotpost AAA methods).

Version used is Mikrotik v5.17 + freeradius 2.1.8 + Radius manager (3,9 + test on v4)
By reading the forum, i found out we need to use Mikrotik-Xmit-Limit-Gigawords but I don’t know how ??

Here is the freeradius debug output (where we see the problem)

Exec-Program output: Mikrotik-Xmit-Limit=> 5368709120> ,Session-Timeout=2459897,Framed-Pool=“XXX”,Session-Timeout := 7200,

Exec-Program-Wait: value-pairs: Mikrotik-Xmit-Limit=> 5368709120> ,Session-Timeout=2459897,Framed-Pool=“XXX”,Session-Timeout := 7200

Exec-Program: returned: 0

++[exec] returns noop

Sending Access-Accept of id 4 to XXXXX port 60418

Mikrotik-Xmit-Limit = > 1073741824

Session-Timeout := 7200

Framed-Pool = “nat-perso”

Finished request 0.

thank you
