When Mikrotik Reboot I lose Sit1 interface

When Mikrotik Reboot I lose Sit1 interface I have to re eter info from my tunnel provider .

Hi hatchetheavyhaul,

What router model and what version are you running at present?
Is this a problem that has only just started happening after an upgrade or is it ongoing for a while?

Are you able to repeat the problem (eg: does it happen after every reboot or only sometimes?) and have you sent an email to Mikrotik support with this information?
