connect VPN from internet fails

Hi folks,
I have a problem access VPN server from internet but I can access the VPN
server from the same 4-ports router.
Router: Netopia R910
VPN server: Win Server 2003,
NIC0(Internet):
IP: 64.146.141.131
Subnet: 255.255.255.248
Gateway: 64.146.141.129
NIC1(Company Network):
IP: 192.168.111.105
Subnet: 255.255.255.0
Gateway: 192.168.111.1

When I connect a XP client to the router on
IP: 64.146.141.132
Subnet: 255.255.255.248
Gateway: 64.146.141.129
the VPN connection is good. However, I can’t connect to the VPN server from
my home.
I contacted our ISP and they said all ports are open.
I did a lot research but still can’t solve the problem. Now I guess that
maybe the router doesn’t support VPN.
Could the router be my problem? How can I be sure the router supports VPN?
If the router is not an issue, what could cause my problem?
Thx in advance!

Netopia R910 is support VPN. What's the error code? I tested the port 1723 which should be open for PPTP but it is not open.

Hi Robert,
IP 64 should be 66.
Please try 66.146.141.131.
Error codes are 638,678. Each time I received different error code.

Thx again.

From the interface(NIC0) under NAT/Basic Firewall, I found some information
might be useful.
Total Mappings(3), Inbound packets translated(29),Inbound packets
rejected(10), Outbound packets translated(26)

Does this mean that the VPN connection were rejected?
Thx.
