Intrex.Net always recommends that dedicated access customers purchase a dedicated router such as an Ascend Pipeline when connecting to our service. However, it is possible in some circumstances to use a PC as a router. On this page, we will examine a couple scenarios and explore the possibilities of using a PC as a router. Note: If you are not connecting a network to the Internet, not doing web hosting for virtual domains, or for some other reason did not receive a block of IP addresses with your Intrex.Net account, you only have to perform step #1 of the procedures below.

Requirements

1. Dedicated account with Intrex.Net.
2. Windows 95 (with DUN 1.3), Windows 98, Windows NT or Linux server. Other UNIX operating systems will also work.
3. A working analog modem (for Dedicated analog accounts), an ADSL modem (for Dedicated ADSL Accounts), or ISDN Terminal Adapter (for Dedicated ISDN accounts).

Dedicated analog (33.6/56K), ADSL, and ISDN (64K and 128K) accounts with Windows NT

1. Set up NT as if you were dialing into a simple dialup account. These instructions can be found at the Windows NT4 configuration page.
2. If you were assigned a block of IP addresses with your account, assign the first IP to the network card of your NT server. If you do not have a network card (standalone server doing web hosting?), install the Microsoft loopback device and assign the IP addresses to that device.
3. Enable IP forwarding in the Network Control Panel under the Routing tab of the TCP/IP protocol.
4. Add the following to the NT registry* using regedit under
   \HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RasArp\Parameters
   add DisableOtherSrcPackets as a DWORD Value with value 0

* If you are not familiar with regedit, the NT registry, or networking do not attempt this. Please schedule an appointment for someone to make these settings for you.

Dedicated analog (33.6/56K), ADSL, and ISDN (64K and 128K) accounts with Windows 95 (DUN 1.3 is required) or Windows 98

1. Set up Windows 95/98 as if you were dialing into a simple dialup account. These instructions can be found at the following locations: Windows 95, Windows 98.
2. If you were assinged a block of IP addresses with your account, assign the first IP to the network card of the Windows 95/98 computer which will make the direct connection to Intrex.
3. Add the following to the Windows registry* using regedit under
   \HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Vxd\Mstcp\
   add EnableRouting as a STRING Value with value 1
   (Note: "EnableRouting" is case sensitive)

* If you are not familiar with regedit, the Windows registry, or networking do not attempt this. Please schedule an appointment for someone to make these settings for you.

Dedicated analog (33.6/56K), ADSL, and ISDN (64K and 128K) accounts with Linux*

1. Set up Linux as if you were dialing into a simple dialup account. Limited instructions can be found at the Linux configuration page.
2. If you were assigned a block of IP addresses with your account, assign the first IP to the network card of your Linux server. If you do not have a network card (standalone server doing web hosting?) you will have to use the "Dummy network driver" included in the Linux kernel.
3. Enable IP Forwarding in the kernel.
4. Re-build your kernel if necessary.

* If you are not familiar with Linux, the Linux kernel, or networking do not attempt this. Please schedule an appointment for someone to make these settings for you.
