I have the following topology working but i would like to be able to filter the traffic using a software router such as Zentyal.
Current [INTERNET] === [Cisco 2600] ===[Cisco Switch] === [Machines]
Proposed [INTERNET] ===[Zentyal] === [Cisco 2600] ===[Cisco Switch] === [Machines]
The cisco router is performing routing-on-a-stick on interface f0/1 and I set up a gateway of last resort to send traffic with unknown destination to interface f0/0 (connected to the Zentyal router) using the command ip route 0.0.0.0 0.0.0.0 f0/0.
Obviously the switch is using VLANS- which can ping each other.
The end devices cannot connect to the internet though and I'm not sure where/if im going wrong
