This is the last version of ARA that will run on 68k systems.
From the Read Me:
ARA 3.0 is a major upgrade from the previous version, ARA 2.1. ARA 3.0
represents a complete rewrite, and offers a merging of capabilities
previously requiring two software packages: ARA and OT/PPP.
New for ARA users:
* ARA 3.0 is rewritten "from the ground up" using native Open
Transport interfaces, and runs native on PowerPC based personal
computers.
* ARA now supports the open PPP standard, and can be configured to
connect to multiprotocol PPP servers using both AppleTalk (ATCP)
and TCP/IP (IPCP) concurrently, or can be configured to connect to
PPP servers at Internet Service Providers (ISP's). ARA can now
call your office or the Internet.
* ARA 3.0 offers Open Transport-style control panels, now fitting in
with modern Mac OS human interface design and is now consistent
with the rest of Open Transport.
* Automatic detection of server protocol support (ARAP or PPP).
* ARA 3.0 is scriptable.
* ARA 3.0 includes AppleGuide Help.
* A Control Strip Module is included.
* The Remote Access control panel includes send and receive
indicators of network traffic.
* Open Transport 1.1.1 or later is required.
New for OT/PPP users:
* ARA 3.0 Client includes a control strip module.
* The Remote Access control panel replaces the PPP control panel.
* The Remote Access control panel includes a triangle control to
reduce the window size.
* AppleTalk PPP (ATCP) support is now included.
I have tested using Basilisk II on my modern PC + a USB to serial
connection + Macintosh SE connecting over PPP and also with the SE
running the ARA 2.0 client
Note: when using PPP to connect to the host system, you can not use
the host system as a bridge to connect to the internet, you need a
second system for that.

CPU with 8MB of RAM. Supports the ARA 3.0, ARA 2.x and PPP clients.
Open Transport version 1.1.1 or later is required in order to install
Apple Remote Access 3.0. Your Apple Remote Access 3.0 CD comes with
