The router provided by ISP is very poor perfomance and I want use a Cisco 800 router to replace. When I config the router It's not working. I'm not sure whats the problem.
The ISP: Angola ZAP Fibra
Here is the information I get from router by ISP:
Here are my setting for the Cisco 800:
configure terminal
! Configure the DHCP pool to assign addresses to internal hosts
ip dhcp pool vlan1pool
network 192.168.88.0 255.255.255.0
default-router 192.168.88.1
dns-server 8.8.8.8
! Do not assign addresses 1 to 30
ip dhcp excluded-address 192.168.88.1 192.168.88.30
! This is the LAN facing interface of the 800 router. Used as gateway for PCs
interface vlan 1
ip address 192.168.88.1 255.255.255.0
ip nat inside
no shut
! Interfaces FE0 to FE3 are Layer 2 interfaces
interface FastEthernet0
no shut
interface FastEthernet1
no shut
interface FastEthernet2
no shut
interface FastEthernet3
no shut
! This is the WAN interface getting address via DHCP from the ISP
interface FastEthernet 4
no shut
ip address dhcp
ip nat outside
! Configure NAT. All internal hosts will be nated on the WAN interface
ip nat inside source list 1 interface fastethernet4 overload
access-list 1 permit 192.168.88.0 0.0.0.255
ip route 0.0.0.0 0.0.0.0 fastethernet4
Could anyone can show me the right way?
