Unanswered Question

Hi,

i want to ask for this:


We bought 1811 router and want to make backup internet connections.


Connections are both using WAN ethernet ports. When primary connection will not work, router use backup line on another ethernet interface. When primary connection will be avaiable again, it switch back to primary connection.


Backup will based on ping-ing some internet address. When this ip adress will be unaviable then router switch to other line.


Can someone help me how to configure this scenario?


Thanks.

-----------------------

So i have two internet connections 192.168.1.101 (primary, 192.168.0.101 (backup) and inside interface vlan1.


On interface vlan 1 will be server with address f.e.: 192.168.3.12 and 192.168.3.150 (iLo).


How should i forward/public ports 25,443 on router that this services will be avaible from to internet users? static translations, i think?


Thanks.
