Configuring cisco 1921

Philipvanbeeck

Level 1

Hi,

I'm trying to configure a cisco 1921 with our new provider and I am having some problems. With the config below I can ping hosts from the router, but not from the private ip's. The info I got from the ISP:

wan route: x.x.x.220/30
isp ip address: x.x.x.221
customer ip address: x.x.x.222
public ip's: y.y.y.224/29

Any help would be appreciated.

Philip

public ip's: y.y.y.224/29 are assigned for your hosts and you haven't done so in your router configuration.

The easiest approach is configuring nat pools

For instance:

ip nat pool NETPRO y.y.y.y.201 y.y.y.206 netmask 255.255.255.248

ip nat inside source list 1 pool NETPRO

access-list 1 remark CCP_ACL Category=2

access-list 1 permit 192.168.0.0 0.0.0.255
