i recently bought a router 1811 8-port switches and 2xFE ports
The network goes like this
(webserver_set_1)-----(VLAN1) ----- (FE0) 111.222.333.444
(webserver_set_2)-----(VLAN2) ----- (FE1) 444.333.222.111

Below are there my configuration. set_1 hosts domain.com, set_2 host apps.domain.com.
I ran into these problems.

1. from set_1, i tried to access http://domain.com and traffic was blocked somehow.
2. from set_2, I tried to access set_2 via HTTP request http://apps.domain.com (or vice versa), instead reading responses from the webservers, I was directed to GUI interface of the router it self.
3. I was ABLE to establish communicate between two VLANs

I'm not sre whatwas going wrong. :shock:
Can you please help?

permit ip 192.168.1.0 0.0.0.255 any
 deny   ip 192.168.1.0 0.0.0.255 192.168.0.0 0.0.0.255

ip access-list extended list-2
permit ip 192.168.0.0 0.0.0.255 any
deny   ip 192.168.0.0 0.0.0.255 192.168.1.0 0.0.0.255

(Replication)
