Hello,
I know this is mikrotik forum, but it is very responsive forum. I hope I will finally find answer to my question. I try to ask from the view of mikrotik side.
Does anyone suspect where can be difference between debian network config, PPTP and mikrotik network config, PPTP.
In case of debian server setup is configured right. Why can be these packets blocked somewhere? Can it be bad checksum of tcp packets? Or can it be HOSTNAME(local) in TCP data of making pptp connections? MikroTik sends HOSTNAME(Mikrotik).
Main problem is that 1 of 50 same HW and SW clients cant connect to VPN server after we switched PPTP server from miktorik to debian. More precisely in new server GRE packets are lost for this client, but I dont know why.
According to logs from miktorik and debian, this client cant connect exactly after we replaced VPN server.

Thanks.
