Disabling VAC for local server

I’M NOT TRYING TO CREATE A KIND OF HACK/CHEAT/EXPLOIT

Thanks, my ISP it’s a really shit, seriously, my internet fails each 30 minutes, and i highly need to work on MP because gmod seems to crash when i play on SP (Something that i’m used because i don’t develop on singleplayer)

But seriously, i’m freaking tired of being kicked for Invalid USERID ticket after my internet returns…So…Can i disable vac on my local server for avoid that kind of messages? (I think that’s VAC because i didn’t had that kind of messages when i played SP and i don’t think that VAC run on SP)

put -insecure in the startup command line

Thanks! It didn’t kicked me yet
