system onewandialup

This command can force the router to have no more than one remote connection

active at a time. (Multiple links to the same remote are allowed.) To see the current

setting, use the command system list and check the One WAN Dial Up line.

This command is useful when security concerns dictate that the router have only one

connection active at a time. For example, if set to on, the router cannot connect to

both the Internet and another location (such as your company) at the same time.

A connection is only generated when data is forwarded to the remote router (dial-on-

demand); Permanent links cannot be automatically generated.

The command allows multiple connections to the SAME location and supports the

PPP Multi-Link protocol. To do so, at system startup time, the router examines each

remote entry. If it finds only one remote enabled, it leaves the remote enabled. If it

finds more than one remote enabled, it disables every entry that does not have a

protocol of PPP or PPPLLC. It sets the minimum number of active links (remote

minLink) to 0 (zero) on the enabled entries; if the command did not perform this

function, connections to multiple destinations would not be possible (since the link to

the destination with minLink=non-zero would be active).

This system oneWANdialup command complements the system wan2wanforwarding

command. That command allows multiple connections to different locations to be

active at the same time but stops traffic from passing from one WAN connection to

another.
