Can't log to mikrotik via VPN

Hello guys,

I’ve encountered the following problem with both OVPN and SSTP. After the initial set up of the server and the client I’m able to connect to the server and I have access to the local network behind the VPN server. I have access to one of the servers behind the Tik and I have ping to the mikrotik router on which the VPN server is set. However I’m not able to connect to my mikrotik devices (either the gateway device on which the VPN is or the mikrotik devices behind it) via winbox from the client side. I’ve even tried to allow http on the tik but it still can’t log (normally only winbox connection is allowed)

According to the firewall rules - I’m using the default firewall with slight adjustments which should not impact the connection. I’m also using src-nat for both my WAN connections. Additional to this I’m allowing the VPN port in the firewall i.e.

/ip firewall filter
add chain=input protocol=tcp dst-port=1194 action=accept place-before=0 comment=“Allow OpenVPN”

respectively tcp dst-port 443 when I’m using SSTP.

I know that I’m missing something obvious but till now I wasn’t able to find it out.
