This document gives a general overview of TCP/IP LAN to LAN. More details can be found in the 833 User Guide (Configuring the User Database and Cofiguring the Protocols)

Dial in router:

1. Create a User profile on the Perle's User Database.
2. Disable "Use Standard User Profile" to enable custom features.
3. In the User Profile tab, enable "Enable Lan To Lan". This allows a remote Router to access the 833.
4. For a Dial in router configuration do not configure any parameters in the Lan To Lan tab.
5. In the Protocols tab, you can specify the Protocol, Compression, and Addresses (note that some routers may not support all methods of compression).
6. The IP address used by the remote router WAN port can be allocated by the Perle with a fixed IP address in this user profile, from the WAN IP Pool, from the WAN DHCP scope or be fixed on the router. The Perle's TCP/IP Protocol configuration must support the type you wish to use.
   Note: The Perle 833IS or 833AS do not supported an unnumbered link.
7. This completes the User Profile configuration.
8. In the Protocol -> TCP/IP section you must create a static route if you are using not using RIP (on both the Perle LAN and WAN interfaces and the remote router). When defining a static route to a remote site you must specify the Destination Port as WAN and select the Lan To Lan User profile for that connection.

Dial out to router:

The Perle 833IS and 833AS can offer a permanent connection or a dial on demand connection.

The configuration continues from the above "Dial in router" configuration.

In the User Database profile Lan To Lan tab, specify the remote router authentication information. The Perle 833IS and 833AS supports both PAP and CHAP. If the router is enabled for a Secondary CHAP challenge the Perle will reply with the a UserID = P833 and the Password = PERL.

1. Configure the remote site's dialing information.
2. If you require a permanent connection established when the 833IS or 833AS is booted up, enable "Enable Auto Connect".
3. This completes the User Profile configuration.
4. In the Protocol -> TCP/IP section you must create a static route if you are using Dial On Demand, or if you are using Auto Connect when the remote and local site do not support RIP (if RIP is used on the Perle's LAN and WAN interface then routing information will be updated automatically).
   When defining a static route to a remote site you must specify the Destination Port as WAN and select the Lan To Lan User profile for that connection.

Trouble Shooting:

Cannot ping remote site.

Use the "trace route" utility to map the path that the packets take to get to the remote site.
Note: By default the Perle is enabled for RIP on the LAN and WAN interfaces. If RIP is disabled on the Perle LAN interface then routing information will be required on the local LAN devices. The LAN devices will not know how to route packets to the remote network. You can add a route to each workstation or in the default router on the LAN.

Verify with the Perle's event log that the Lan Dialout (LDO) occured:

Resource event log: S1CH01 S1M04 : allocated to port 9 (LDO)

If you are using RIP then you can view the RIP tables through the Statistics -> IP screen.

Note: a quick test to verify that the outbound call is connecting is to configure the Lan To Lan for Analog (if your ISDN subscription supports this) then set the telephone number for a local telephone. When the LDO occurs the telephone should ring.

Note: The 833's do not support unnumbered links.
