I'm trying to set up pptpd server. It's virtualized and works, when connecting from LAN. When I'm trying to connect from the outside using the same Win XP laptop, I get error 649, no syslog messages on pptpd server. The firewall is also Ubuntu, all policies are ACCEPT, ports are forwarded:
Code:
Chain PREROUTING (policy ACCEPT)
target  prot opt source            destination  
[...]
DNAT    gre  --  anywhere          anywhere         to:192.168.0.12 
DNAT    tcp  --  anywhere          anywhere         tcp dpt:1723 to:192.168.0.12
[...]
modules are inserted:
Code:

What am I missing?
