Hello,
Yes, I plan to update the version later.
I also tried enabling the specific NAT rule for ether4 marked #0, and it didn't work either. The result was exactly the same: I could access the internet from the Mikrotik, but not from the internal network.
Flags: X - disabled, I - invalid, D - dynamic
0 chain=srcnat action=masquerade out-interface=ether4 log=no log-prefix=""
1 ;;; defconf: masquerade
chain=srcnat action=masquerade out-interface-list=WAN log=no log-prefix="" ipsec-policy=out,none
2 ;;; srnat-sslvpn
chain=srcnat action=accept src-address=a.b.c.0/24 dst-address=d.e.1.f.0/24 log=no log-prefix=""

It would be a great help if anyone could give me some other ideas. I can't find the problem. I've even considered that it might be related to the PPPoE configuration, but this is really strange what's happening with the Mikrotik.
