Hi, I need some help configuring a 1811 for routing 2 networks and IPS. and a ASA 5505 for Firewall, content filtering and vpn.


Right now I have them setup on a test lan. I have the 5505 and content filtering working , but I am having problems with routing on the 1811


Corp 192.168.1.1

remote site 192.168.2.1 Via T1 Cisco 1720 routers

Sorry for the lack of info.


right now our production network is like you have it ASA--router---t1---router.


conf t

int f0

ip address 192.168.1.10 255.255.255.0

no shut

int s0

ip address 192.168.254.1 255.255.255.252

service-module t1 clock source internal

no shut

exit

ip route 0.0.0.0 0.0.0.0 192.168.1.2

ip route 192.168.2.0 255.255.255.0 s0

exit

Remote:

conf t

int f0

ip address 192.168.2.10 255.255.255.0

no shut

int s0

ip address 192.168.254.2 255.255.255.252

no shut

exit

ip route 0.0.0.0 0.0.0.0 s0

exit


We are replacing all our netgear and 3com crap with all Cisco. so the flow is

ASA--cat2960switch--1720--T1--1720--CatExp500switch--CatExp500switch

I was thinking of having the 1811 as the core router. so the 1720 would point to the 1811, the 1811 to the ASA.

I dont think IPS will work like that. It wants to monitor data from a Wan. So do i need to connect my ASA 5505 to FE0 on the 1811 and make it Look like a wan?

do i need to Trunk them? or Vlan between them?
