RouterOS pptp-server disconnect

I have noted, that when the RouterOS clients that use Windows XP with firewall enabled on the interface would disconnect after 15 minutes (actually 933 seconds according to the RouterOS logs).

Disabling the firewall on the Windows XP client ‘solves’ this problem.

Any ideas?

With the current version, it works fine for us.

I suggest either update the XP or send a supout file to us.
