My setup is like this
on ether1 I have hotspot running and all users function without problems.
We are currently into transition from hotspot to PPPoE.
I do that by creating EoIP tunnel and bridging it with ether1.
Users that go via that tunnel to PPPoE server have internet access without a problem.
But users who remained on hotspot have troubles accessing certain websites, like kurir.rs, blic.rs and making calls over Viber.
This problem was first noticed on RB1100AHx2 with 6.27RoS. And I resolved the issue with downgrading to 5.26.
Now same is happening on RB433AH on 6.28. I think that this is a bug because downgrading ROS makes problem dissapear.
But this router is on very remote location so I'm reluctant to downgrade because couple of times after downgrading router got stuck in reboot loop.
Can someone help me troubleshoot this and solve it.
I will provide any aditional info needed.
