Hello. I'm a newbie so I use graphical interface to configure my cisco router 871
I have 2 networks
n1: 10.0.0.0 /24
n2: 192.168.1.0 /24
192.168.1.252 is the gateway to internet
n1 has not access to the internet
n2 has the access to the internet using the gateway 192.168.1.252
I want n1 to use the internet access of n2
so I have connected n1 to fe0 with ip 10.0.0.250 and create the vlan1.
n2 is connected to fe1 with 192.168.1.251 ip and create vlan 2
after that I have created a nat between vlan1 and vlan2. No rules are defined .
on n1 each PC has 10.0.0.250 as default gateway and 192.168.1.252 as DNS server
from n1 I can ping the default gateway 192.168.1.252 but I can't access to the net. I have the dns resolution from n1, i can for example get the ip adress of cisco server, but from internet explorer I always have "connecting to http://www.cisco.com" but no connection. The ping give me the ip address but no answer from the server!
Is someone can help me, but only with graphical interface or maybe told me if my configuration is very bad!!!
I have created a NAT because I can't modify the default gateway on n2 and so the n1 network is not sawn by the default gateway 192.168.1.252
