Mikrotik as SSTP client to SoftEther

[Diserted]

Hello!
I have strange trouble:
created account, created local bridge, configured dnsmasq
when i use that account on windows -
route add 192.168.180.180 255.255.255.255 192.168.33.1(bridge ip) - everything great
from mikrotik
added route to 192.168.33.1 via sstp interface - ping to 192.168.33.1 ok
added route to 192.168.180.180 via sstp - no ping to 192.168.180.180
checked tcpdump -i tap_mikrotik - no packets to 192.168.180.180

Why? Tried all types of routes, another mikrotik - nothing helps.
Same account from Win11 and SoftEther client - everything is great.

routing table from server with SoftEther -

192.168.31.0/24 dev tap_otp proto kernel scope link src 192.168.31.1
192.168.32.0/24 dev tap_smart proto kernel scope link src 192.168.32.1
192.168.33.0/24 dev tap_mikrotik proto kernel scope link src 192.168.33.1
192.168.34.0/24 dev tap_adminotp proto kernel scope link src 192.168.34.1
192.168.35.0/24 dev tap_adminsmart proto kernel scope link src 192.168.35.1
192.168.180.0/24 dev ens224 proto kernel scope link src 192.168.180.1

What can be wrong?

So the scheme:

office1 network on second ethernet card(192.168.180.180 for example) ------ linux server with SoftEther(local bridge 192.168.33.1, eth 192.168.180.1) <------- mikrotik sstp-client with office2 network
I need to access office1<>office2 computers, without nat
is it possible? it was ok on pure openvpn
now i'm trying to reach 192.168.180.180 from mikrotik and can't

Is it possible that SoftEther filters packets, like it discovered there?

Did you connect with Windows SE or SSTP client?
If SE, then check it with SSTP.

If SE, then check it with SSTP.

Hello solo, thank you for fast answer!
Checked Win11 sstp client - fail, with default and static route - no luck. Can ping only server.
So no way to do it with softether?

[solo]

Probably not. As you can see in https://www.vpnusers.com/viewtopic.php?f=7&t=67633 the SSTP issue is still work in progress :-)
The TO-DO list:
- check it on Windows SE server (I tested SSTP only on Linux)
- if it works on Windows, try Linux with soft tap, not direct NIC bridging

I tried linux with soft tap, securenat - nothing.
Decided to use virtual mikrotik for sstp server for mikrotiks - everything works great.
Thank you for help!

I have the same problem with wrong IP address?
Were you able to solve it?
