Allow If an alternate gateway on the LAN has an IP address in the same subnet as the Zyxel Device's
Asymmetrical
LAN IP address, return traffic may not go through the Zyxel Device. This is called an
Route
asymmetrical or "triangle" route. This causes the Zyxel Device to reset the connection, as the
connection has not been acknowledged.
Select this check box to have the Zyxel Device permit the use of asymmetrical route topology
on the network (not reset the connection).
Note: Allowing asymmetrical routes may let traffic from the WAN go directly to the
LAN without passing through the Zyxel Device. A better solution is to use virtual
interfaces to put the Zyxel Device and the backup gateway on separate
subnets.
