Pptpd nelze navázat spojení

Ahoj,
vím, že se to tu již řešilo 150x a jinde milionkrát. Vezmu to tedy rychle a fakticky.

Mám Turris Omnia
potřebuji na něm zprovoznit pptpd

mám nainstalovány a povoleny všechny potřebné kernel moduly

/etc/sysctl.conf

net.netfilter.nf_conntrack_helper=1

progrepovaný lsmod

V pptdp konfiguraci si myslím, že není problém v případě potřeby dodám

ve firewallu mám

Při připojení Windows10 klienta mi hlásí, že spojení bylo ukončeno ze strany serveru

V logu pptpd na turrisu mám

Zapnul jsem logování na WANu, ale neobjevilo se tam nic, co by se týkalo pptpd portu nebo GRE protokolu
Co dělám špatně?

To spis vypada, ze to odpojily ty windowsy (soudim dle Received PPTP Control Message (type: 12)). Nemate nejak spatne nastavenou autentizaci/kompresi a dalsi veci? GRE spojeni zjevne proslo… eventvwr na windows nic zajimaveho nepise?

Zkuste to z nejakeho jineho klienta - Android, Linux… Treba se z logu dozvite vic.

A doufam, ze se pripojujete opravdu z WAN - pokud by router bezel ve stejne siti, ze ktere se pripojujete, tak s tim jsem vzdycky mel problemy…

Jo vypadá to, že jsem vážně debil :slight_smile:
Pokud androidu vypnu MPPE, tak se připojí, takže jdu se šťourat v pptpd configu, díky, já jsem byl pořád přesvědčený, že chybu mám v networkingu, protože v něm nejsem silný v kramflecích.
