LAN-to-LAN IP Connection
Troubleshooting

- Introduction

This configuration note explains how to set up two Prestige routers for a LAN-to-LAN connection. Once the connection is established, the workstations on both LANs will be able to perform any TCP/IP applications (e.g., FTP, Telnet, etc.). There will be three items that you need to set up. These are workstation and the two Prestige routers.

- Configuration

- Setting up the workstation on both LANs

To set up the workstations, you will need to set the following parameters:

- IP Address-the IP address assigned to the workstation itself
- Subnet Mask-the subnet mask used for your network. Class C networks generally use a 24-bit netmask DNS (Domain Name Server) Address-enter the IP address of the DNS server
- Default Gateway-the IP address of the Prestige, the default gateway for LAN1 is Prestige 1 and for LAN2 is Prestige 2.

The procedure for configuring these parameters for the workstations may differ depending on the type of TCP/IP networking software you are using on your workstations. If you are unfamiliar with how to set these parameters, you can refer to the technical notes corresponding to your software.

For Windows 9x, please go to 'Win9x>Control Panel>Network>TCP/IP-Network Adapter' for finishing the above settings.

- Setting up the Prestige 1 & Prestige 2

Before configuring the two remote nodes for this application, you need to complete the following settings first in each Prestige.

- General Setup in SMT Menu 1-enter the system information.
- ISDN Setup in SMT Menu 2- configure the ISDN parameters.
- Ethernet Setup in SMT Menu 3-enter the IP address of the Prestige and enable the DHCP server if it is required.
- Remote Node Setup in SMT Menu 11

- Prestige 1 Setup

1. Ethernet Setup in SMT Menu 3

`Menu 3.2 - TCP/IP and DHCP Ethernet Setup` `DHCP Setup:` `DHCP= None` `Client IP Pool Starting Address= N/A` `Size of Client IP Pool= N/A` `Primary DNS Server= N/A` `Secondary DNS Server= N/A` `TCP/IP Setup:` `IP Address= 202.113.5.1` `IP Subnet Mask= 255.255.255.0` `RIP Direction= Both` `Version= RIP-2B` `Edit IP Alias= No`

2. Remote Node Setup in SMT Menu 11

`Menu 11.1 - Remote Node Profile` `Rem Node Name= LAN2 Edit PPP Options= No` `Active= Yes Rem IP Addr= 203.66.113.1` `Call Direction= Outgoing Edit IP= No` `` `Incoming: Telco Option:` `Rem Login= Transfer Type= 64K` `Rem Password= Allocated Budget(min)=` `Rem CLID= N/A` `Period(hr)=` `Call Back= N/A Schedules=` `Outgoing: Carrier Access Code=` `My Login= test` `Nailed-Up Connection= No` `My Password= ******** Toll Period(sec)= 0` `Authen= CHAP/PAP Session Options:` `Pri Phone #= 5007025 Edit Filter Sets= No` `Sec Phone #= Idle Timeout(sec)= 100` `Press ENTER to Confirm or ESC to Cancel:`

Key Settings:

- Select the 'Active' field to 'Yes'
- Select the 'Call Direction' to 'Outgoing'
- Enter the correct node account in 'My Login' and 'My Password' fields
- Enter the phone number of the remote router in the 'Pri Phone #' field
- Enter the IP address of the remote router in 'Rem IP Addr' field
- Enter the idle timer in the 'Idle Timeout' field for dropping the call if there is no data traffic between the two remote nodes

- Prestige 2 Setup

1. Ethernet Setup in SMT Menu 3

`Menu 3.2 - TCP/IP and DHCP Ethernet Setup` `DHCP Setup:` `DHCP= None` `Client IP Pool Starting Address= N/A` `Size of Client IP Pool= N/A` `Primary DNS Server= N/A` `Secondary DNS Server= N/A` `TCP/IP Setup:` `IP Address= 203.66.113.1` `IP Subnet Mask= 255.255.255.0` `RIP Direction= Both` `Version= RIP-2B` `Edit IP Alias= No`

2. Remote Node Setup in SMT Menu 11

`Menu 11.1 - Remote Node Profile` `Rem Node Name= LAN2 Edit PPP Options= No` `Active= Yes Rem IP Addr=202.113.5.1` `Call Direction= Outgoing Edit IP= No` `` `Incoming: Telco Option:` `Rem Login= Transfer Type= 64K` `Rem Password= Allocated Budget(min)=` `Rem CLID= N/A` `Period(hr)=` `Call Back= N/A Schedules=` `Outgoing: Carrier Access Code=` `My Login= test` `Nailed-Up Connection= No` `My Password= ******** Toll Period(sec)= 0` `Authen= CHAP/PAP Session Options:` `Pri Phone #= 5007025 Edit Filter Sets= No` `Sec Phone #= Idle Timeout(sec)= 100` `Press ENTER to Confirm or ESC to Cancel:`

Key Settings:

- Select the 'Active' field to 'Yes'
- Select the 'Call Direction' to 'Incoming'
- Enter the correct node account for the dial-in router in 'Rem Login' and 'Rem Password' fields
- Enter the IP address of the remote router in 'Rem IP Addr' field.

After you have finished the above settings, you are ready to make a test for this connection from Menu 24.4.5- 'Manual Call' by entering the node number.

`Menu 24.4 - System Maintenance - Diagnostic` `ISDN System` `1. Hang Up B1 Call 21. Reboot System` `2. Hang Up B2 Call 22. Command Mode` `3. Reset ISDN` `4. ISDN Connection Test` `5. Manual Call` `TCP/IP` `11. Internet Setup Test` `12. Ping Host` `Enter Menu Selection Number:` `Manual Call Remote Node= N/A` `Host IP Address= N/A`
