How to configure these on Cisco Router 881?
Posted on 2013-12-11
I want to setup this router as an Internet router for the following objectives:
1. There are 2 interfaces - VLAN1 for internal network, and FE4 as WAN interface for Internet line. I have subscribed a Internet line with the ISP on dynamic IP plan. What I have to configure on the WAN interface is just set it to DHCP, and all ip addressing will be allocated. These include, IP assigned to the WAN interface, subnet mask, default gateway, dns server ips, etc.
How should set these settings on the FastEthernet4 interface? How about the default gateway? Shall I point it to the FE4 or else?
2. I also need to setup this router as a DHCP server for my network - 192.168.100.0/24. There are few IPs have been assigned to few servers, and no-changeable. These IPs are,
.100.5, .100.25, .100.144, .100.188; how can I exclude these IPs on my router, suppose my DHCP pool is ranging - .100.51 - .100.200?
thanks in advance.
