Configuring Proxy ARP

This section describes how to configure PortServer TS 8/16 for Proxy ARP.

Related Information

See the set forwarding command in the Digi One/PortServer TS Command Reference.

Starting Point

This procedure assumes that you have signed on as root and have or will configure modems, modem scripts, devices, and filters for routes that use serial lines.

Procedure

1.Configure the links over which packets will be routed using a set user command. This command must specify (on the ipaddr field) a specific IP address for the remote system using the Proxy ARP service.

2.Configure PortServer TS 8/16 for Proxy ARP by supplying a set forwarding command that spec- ifies the following:

state=passive

proxyarp=on

Example

In this example, PortServer TS 8/16 provides Proxy ARP services to a remote host.
