Re: VPN PPTP problem

Hello David,

Thank you for your reply.

If you plan to change the SBS external NIC IP scheme from 192.168.1.10 to
192.168.9.10, we also need to change the internal NIC IP of your Firebox
from 192.168.1.2 to 192.168.9.2. Then, the default gateway of the SBS
external NIC should point to the Firebox internal NIC IP. Like this:

IP Address. . . . . . . . . . . . : 192.168.9.10
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.9.2
DNS Servers . . . . . . . . . . . : 192.168.2.5
Primary WINS Server . . . . . . . : 192.168.2.5
NetBIOS over Tcpip. . . . . . . . : Disabled

I suggest we change the Firebox internal NIC IP first, then we need to run
the CEICW to change the SBS external NIC IP. At the end, we need to change
the Firebox port forwarding rules, to ensure it forward VPN necessary ports
to the SBS external new IP address.

Additional, the server packets capture log is not our SBS log, I unable
analyze it for you. As a whole, if you set the same IP scheme in the router
link, you may experience many IP router issue. Therefore, change the IP
scheme is recommended.

I hope the information will give you some help.

Thanks and have a nice day!

Best regards,
