We've got some strange behavior of M0n0wall 1.2b9 from its PPTP subsystem: when client's connection
comes from very high ports (e.x. 35000-65000) MPD can't answer back to it, like the answer is
dropped by firewall. If it comes from high ports range 1024-3500 or like that - everything's fine,
VPN works.
IPF table has no any "high ports deny" rules.
Any ideas? :)
