If you are not doing NAT, NetMAX is capable of routing VPN traffic (including PPTP), as long as you are not denying it with the firewall.

There is a VPN patch available for ipmasq (the IP NAT that NetMAX uses) that should allow some VPN clients to be behind the NAT.

You may read up on it at:

http://www.impsec.org/linux/masquerade/ip_masq_vpn.html.

Please note that we can't support your installation of this patch.

For more information about Microsoft VPN and NAT, please see their knowledge base article at:
