Hi. We are 2 IT students trying to configure a router for our school. Our Router is a 1841 with a switch modul.
It is a learning experience for us, where we have to make due with whatever equipment we have.
Thanks for your time!
We are having some problems, first and most important, users cant access the internet.
Users can ping to the routers interfaces. Both on the inside and outside, but cannot communicate with either the firewall or the other way out to the internet.
The idea is. We want to make a failover line going from the router to the ISP. It should only be used if the firewall crash (due to old hardware)
Most important is the line through the firewall to the ISP.
vlan on a switch modul from the router to the user switch. (the router only have to normal interfaces) 192.168.0.1 255.255.255.0
eth0/0 192.168.1.2 255.255.255.252 is the interface to the firewall.
eth0/1 is used as failover to the isp directly.
The firewall is allso our dhcp-server at the moment.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
