Hello,
I have a problem with vpn ikev2 (Windows Client - Mikrotik Router).
When transferring larger files, the connection hangs after about 200Mb - the same every time.
Router shows: ipsec, error, no proposal chosen
in Windows 10: Connection error 0x8007003B.
I turned off the firewall, Antivirus and Windows Search Service in Windows - it did not help.
Could this be some kind of bug in the router configuration?
The problem is protocol independent - same for smb and ftp.
Please help
What is your /ip ipsec proposal setting? Any other setting of the pfs item than none is not compatible with the default IKEv2 settings of the embedded VPN client of Windows. So I suppose the 200 Mbytes are equivalent to 25-30 minutes, which is the interval after which the security association gets rekeyed, and the rekeying fails due to the above. Or maybe the Windows trigger the rekey by reaching some threshold amount of data transported using the SA.
It was pfs. I set it to “none” and everything works.
Thank you Sindy!
