RB751G-2HnD AP seems to block UDP traffic used by 3CX

Hello, good morning,

I´m having problems with the wireless SOHO Gigabit AP RB751G-2HnD http://routerboard.com/RB751G-2HnD used as an access point for wireless 3CX SoftPhones communications to the LAN.

The configuration of the AP is simply bridged to the LAN but aniway it seems to block UDP traffic used for RTP/RTCP or SIP protocols used by 3CX.

Following all 3CX indications we replaced it by another brand AP and it worked. Is there issue about it or any fix to use Mikrotik AP again?

Here I attach the configuration;

Kind Regards.

Hello johnsilver. Yes thanks for the answer, but following 3CX instructions we already disabled it and it still blocks the traffic. Regards

Hello,
I have the same problem. I can only connect using tunnel of 3cx (5090) Did you manage it?
