I use VyOS 1.1.7 as a router with BGP and VRRP only. No NAT. No firewall.
There’s Windows Server 2008 R2 behind VyOS. I need to establish client PPTP session from this server to another point. Link is established but user checking is failed with error 734. There’s “Recv timeout event received for portid=24,Id=0,Protocol=c021,fAuth=0” message in ppp.log.
With other network this server connect to this point successfully.
I’ve tried to use zone based firewall with direct acceptance of GRE protocol in both directions. It doesn’t help.
What should i do to solve the problem?
