Доброго всем времени суток.

  %FW-4-RESPONDER_ZERO_WND_SCALE_FACTOR_INI_NO_SCALE: Accepting packet -Window Scale option for session 172.20.30.85:42103 to 85.142.127.242:80 [Initiator(flag 0,factor 0) Responder (flag 1, factor 0)] Responder sent (1,0) which means no scaling and is equivalent to (0,0)

Помогите разобраться что это такое.

Error Message
%FW-4-RESPONDER_ZERO_WND_SCALE_FACTOR_INI_NO_SCALE: Accepting packet -Window
Scale option for session [IP_address]:[dec] to [IP_address]:[dec] [Initiator(flag
[int],factor [int]) Responder (flag [int], factor [int])] Responder sent (1,0)
which means no scaling and is equivalent to (0,0)
Explanation The firewall has detected that the packet from Responder to Initiator has windows
scaling option, but did not have the scaling option in the SYN packet from Initiator to responder.
Responder sent flag 1 but factor 0, accepting packet because factor was 0, which means no scaling.
Recommended Action Turn on the window scaling option on both Initiator and Responder, or turn off
window scaling on the Responder.

Кто нибудь может объяснить по русски что это и что с ним делать.
На роутере настроен ZBPW.
