Routing issue with SSTP

RouterOS Beginner Basics
1

Hi All

I am very experienced and knowledable on TCP/IP, however, quite new to MikroTik.
I have two sites:
Site 1: Static Public IP
MikroTik as LAN GW (10.0.0.1)
SSTP Host (10.3.0.254/24)
LAN: 10.0.0.0/24

Site 2: Dynamic Public IP
MikroTik as LAN GW (192.168.26.1)
SSTP Client (10.3.0.1/24)
LAN: 192.168.26.0/24

I have enabled the firewall so that all traffic is allowed to all networks. The VPN is up and running.
Site 1 MikroTik can ping Site 2 MikroTik.
Site 2 MikroTik can ping Site 1 MikroTik.

Site 1 workstation (e.g. 10.0.0.16/24) can ping Site 2 workstation (e.g. 192.168.26.99)
However, the very strange thing is that:
Site 2 workstaion (e.g. 192.168.26.99/24) can NOT ping Site 1 workstation (e.g. 10.0.0.16/24)

I have tried everything I can possibly imagine; however, after spending about 2 weeks breaking my head over this, I really cannot figure out what is going on.
Any workstation in Site 1 can connect (via multiple protocols such as CIFS and RDP etc. etc.) to Site 2 100% successfully and quite fast I might add.
However, a workstation in Site 2 cannot ping anything on Site 1, not even the Site 1 LAN GW. The furthest I get is to successfully ping (10.3.0.254/24) from a Site 2 workstation, nothing further.

I cannot figure this out and hopefully someone out there is able to help me.

Thanks in advance for any help you can give!

You should specify route on both sides, than it will work as expected…

On SITE1 mikrotik:
/ip route add distance=1 dst-address=192.168.26.0/24 gateway=10.3.0.1

On SITE2 mikrotik:
/ip route add distance=1 dst-address=10.0.0.0/24 gateway=10.3.0.254

Hi dmitris

Thank you for your input. These routes where added dynamically by the SSTP VPN. However, I have also tried to create them manually. I have also tried creating a mangle route, however, this also didn’t work. Nothing I have tried so far has worked.

Any other suggestions or things to try?
Thank you!
