Raising the tickle packet interval does not ensure that the AURP tunnel is dropped or not brought up. If any application on the local network generates AppleTalk traffic destined for the network at the remote end of the AURP tunnel, the tunnel remains up. For example, if a host on the local network connects to a host on the remote network using remote access software, the AURP tunnel remains up. The AURP tunnel also remains up if a local user selects the Chooser and uses an AppleTalk service that involves a remote zone, such as mounting a remote AppleShare volume.
■In many AppleTalk internets, individual AppleTalk networks come and go. Routers are designed to notify each other at the end of their Update Interval every time there's such a change in the network topology. This will cause the Netopia's WAN link to be brought up. You can opt to minimize what may be unnecessary calls by changing the Update Interval value to some larger value. At the end of this time window if there has been a local AppleTalk network change the Netopia R3100 will call any remote AURP partner and forward the new network information.

You should enable network number remapping if you plan on using AURP when connecting to unknown AppleTalk networks. for example when “Accept Connections from Anyone” is enabled. With remapping, the Netopia R3100 will substitute network numbers not used by your network for the numbers of other remote networks. These safe remappings will only be used by local routers on your network; remote routers will not be aware of the remapping.
When network number remapping is enabled, you must choose a safe range of network numbers as a destination for the remapping. A safe range of network numbers does not intersect your local AppleTalk network’s range of network numbers.
To choose a destination range for the remapping, select From under Remap into Range and enter a starting value. Then select To and enter an ending value. Make sure the range you choose is large enough to accommodate all expected incoming AURP network numbers.
To improve the efficiency of remapping network numbers into a safe range, select Cluster Remote Networks and toggle it to Yes. This setting takes any number of remote networks being remapped and causes them to be remapped into a continuous range.
To override the AppleTalk maximum limit of 15 hops, select Enable
AppleTalk allows a packet up to 15 hops (going through 15 AppleTalk routers) to reach its destination. Packets that must reach destinations more than 15 hops away will not succeed, therefore tunneling from one large AppleTalk network to another could exceed that limit. In such a case, hop count reduction enables full network to network communication.
You have finished configuring AURP.
