SSTP Disconnecting after 2 Minutes

RouterOS General

Router with 6.44v was working fine till last two days from Windows10 inbuilt sstp client. Suddenly showing this behavious. One of the changes done on these period is redirect some subnet traffic to secondary ISP using mangle.

[admin@Mikrotik] /interface sstp-server> serv print

10:55:06 sstp,ppp,info,account user1 logged out, 120 102 356 5 7

Any Idea on this ? Any one notice this issue before. Please, can anyone help me to figure it out. How mangle and NAT are co-related ?

Both NAT and mangle are handlings done by the firewall. As you use mangle to control routing, I would expect that due to some mistake or omission it affects the communication with the SSTP client.

Follow the hint in my automatic signature if you can’t find the aforementioned omission or mistake on your own.
