Mikrotik SSTP + Softether

RouterOS General
1

Please help,

i install on linux VPS (softether VPN solution - sstp, OPENVPN, L2tp etc. ) configure try connect from windows 8 - all OK (on load channel and in standby), working.
Now try configure SSTP on mikrotik and connect to my server

Made configuration, result:

Uptime 01:56:32
Encoding AES256-CBC
MTU 1500
MRU 1500
Local Address 192.168.30.11
Remote Address 1.0.0.1

Some additional info:
make default route =no

Hoh you see all work, ok add nat function, write additional route (on my ISP closed Youtube, but i wanna see pussycat:) )

If connection stay in standby (or i try open 1-2 url) sstp work OK and connection stable. But i try load channel (example open 1 video in youtube) connection lost, and begin recconect.

Please help why that can be.

I have same issue… made a ticket #2015050766000783
Seems to be some issue with MT SSTP client - this does not happen with windows client.

Yes i have same situation, i try update mikrotik up to 6.28, but without result

Looks like a bug with either SofthEther VPN or the SSTP client implementation on Mikrotik.
SoftEther VPN server seems to be pushing the address 1.0.0.1 via IPCP, causing the client to set up a route for it:
local address: 172.30.1.21
remote address: 1.0.0.1 (should be 172.30.1.2)
local network: 1.0.0.1 (should be 172.30.1.0)

route entry:
1 ADC 1.0.0.1/32 172.30.1.21 sstp-vpn 0
(should be : 1 ADC 172.30.1.0/32 172.30.1.21 sstp-vpn 0)

Has also been reported to happen on Ubuntu SSTP clients

I can say for sure that this issue is not present on windows built-in SSTP client

6

I think problem not in route, because when using Windows (default client) remote address 1.0.0.1 and dedault work perfect.

I think problem with different implementation (mikrotik and ethersoft)

7

well this Issue in 6.31， view like youtube or twitter be disconnect
and my use server software is softether

8

I see that problem on all old version include 6.31.

If i forward to Ethersoft only UDP traffic ( ex. SIP + RTP) voice work perfectly i think problem with TCP (and MSS configuration) but not find solution

9

Did someone here find a solution or workaround for this?

Yes, update mikrotik to last version.

I resolve problem after update mikrotik (not remember version)
