I am trying to set up a cisco 2800 series router in my home lab. yes its old, but cheap enough to play around with.
So I am coming up against a problem configuring the router.
I can ping out to the internet from the router directly. so its making a pppoe connection just fine.
I can ping the router from a connected pc which is getting assigned its appropriately assigned ip details. I cant however get an internet connection on that router, pinging googles dns server fails and pages wont load.
I am sure i have missed something but have no clue as to what that might be.
Here are the steps taken to set the configs. fa0/0 connects to a modem, fa0/1 connects to a computer (will be a switch)
conf t
int fa0/0
no shut
pppoe enable group global
pppoe-client dial-pool-number 1
exit
int dialer 1
no shut
ip address negotiated
encapsulation ppp
ip tcp adjust-mss 1442
dialer pool 1
dialer-group 1
ppp authentication chap callin
ppp chap hostname *******
ppp chap password *******
exit
ip route 0.0.0.0 0.0.0.0 dialer 1
exit
conf t
int fa0/1
ip address 10.0.2.1 255.255.255.0
no shut
exit
service dhcp
ip dhcp pool lan1
network 10.0.2.0 255.255.255.0
default-router 10.0.2.1
dns-server 8.8.8.8 8.8.4.4
lease 1
exit
ip dhcp excluded-address 10.0.2.1 10.0.2.25
int fa0/1
ip nat inside
exit
int dialer 1
ip nat outside
exit
ip nat inside source list 1 interface dialer 1 overload
exit

I finally got this sorted.
I am sure there are settings that are not strictly required, though I'm finally able to get my cisco router to provide internet internet to the servers so that's a start. Next is securing and port forwarding but I will update here as I build my configuration up.
