Hi,


I config the 1811 to be a FW. It can filter and block IM service if the PC and workstation are on the VLAN1. It is working properly.


R1

interface VLAN1

ip address 192.168.12.1 255.255.255.0


I will put another router and connect to 192.168.12.0 segment.


R2

Interface FE0/0

ip address 192.168.12.2 255.255.255.0


Interface FE0/1

ip address 192.168.18.2 255.255.255.0


Interface FE0/2

ip address 192.168.19.2 255.255.255.0


I find that all packets of R2 (192.168.18.0/24 and 192.168.19.0/24) are blocked by 1811.


How to configurate the 1811 so that the 1811 can allow those segment go out and protect those two segments?

run some routing protocol (ospf, eigrp) or use static routes.

on r1

ip route 192.168.18.0 255.255.254.0 192.168.12.2


on r2 i think

ip route 0.0.0.0 0.0.0.0 192.168.12.1

Hi,


the routing had been configured.


If I disable the firewall, the packets can access out side.


R1

interface Vlan1

no ip inspect sdm_ins_in_152 in


If I enable fw again, two segment packets are blocked in 1811. any idea?
