Hi,
I have a cisco 800 series ADSL modem / switch, which is configured with the settings described below. This works fine, but i have some questions about it and i want to change some settings:
- how do i enable dhcp for interface Ethernet0 so that computers in my LAN get an IP address between 192.168.1.3 - 192.168.1.100 ? I want one computer to have a fixed ip address: 192.168.1.2 does that require special configuration?
- where do i specify the ip address of the router (at the LAN side) ?
- in my current config i have the following lines that map some ports
ip nat inside source static udp 192.168.1.2 6889 interface Dialer0 6889 untill ... ip nat inside source static udp 192.168.1.2 6881 interface Dialer0 6881
is there another way to specify this, i mean can i map a range of ports with one single line?
regards and thanks in advance, Jeroen
