I will install cisco 1811 (with firewall feature set) to be a firewall to block the ICQ/YM/MSN. one interface is connected to ISP, the next interface is connected to internal
1. how to block the "ICQ/YM/MSN" and permit other traffic? any sample config?
### router config
ip address 210.x.x.1 255.255.255.252
ip nat out side
ip address 192.168.1.1 255.255.255.0
ip nat inside
2. if I build the VPN to another remote branch, how to config it?
e.g. remote branch ip is 192.168.128.1/24
3. how can I setup the DMZ (e.g. 18.104.22.168/28 segment for DMZ)?
