I am looking for information regarding design and configuration of firewall on a Cisco 2801 router.
Cisco 2801 with 2 eth. ports and 5 VLANS configured. The 2 ports connected to Cisco 2950 switches.
Native vlan - 1 (some PCs and servers on this VLAN)
2 Trusted VLANS - vlan 3 and vlan 4
DMZ - vlan 10
Untrusted (ADSL) - vlan 100
I would like to know how to set up the 2801 router such that users on vlan 3 and 4 can connected to the internet. ADSL router(192.168.100.2)is on VLAN 100.
Currently I have set up a default route on the router such that all traffic is forwarded to vlan 100.
ip route 0.0.0.0 0.0.0.0 192.168.100.2
Any ideas how can I get this configured?
