SBS Routing & Remote access changes

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi,

I have a client who has a SBS (Standard) installed with 2 NIC's (one
interfacing the WAN and the other the LAN of course).

They have just implimented a new VOIP Asterisk box on the LAN with a
static IP address. The HO site wants to link other remote sites into
this for Voice trunking and routing etc plus for remote support etc
too. The problem we have is that the Router (NetGear) naturally
cannot route traffic to the port ranges on the LAN side from a WAN IP
address range via the Router.

We have opened up the port ranges on the router to the servers WAN NIC
interface, but we need to be able to also forward these port ranges
from the WAN network interface through to the LAN network interface
(or the IP address of the Asterisk VOIP server).

I see that this is possible for a singe port forward within R&R access
under IP Routing > NAT/Basic Firewall > and then properties of the WAN
network card but not for a port range which is paramount for VOIP
traffic etc.

I know many of you will say should be using SBS Premium instead! but
we are not using this and would like to knwo if there is a wqay of
doing this on SBS Standard (apart from reducing the server to a single
NIC).

Many thanks.
