Cisco Router Issues

This seems so simple but I must have a config issue somewhere and I am missing it.

Assigned Modem IP       xx.xx.xx.29
Allocated IP Block         xx.xx.xx.28/30
Subnet Mask FE0/Modem        

FE0 ip xx.xx.xx.30
ip verify unicast source reachable-via rx allow-default 100
no ip red..
no ip un..
np ip proxy-arp

switchport Vlan1

ip route xx.xx.xx.29 (modem IP)


From router terminal i can ping to internet but VLAN1 via FE2 can only ping router and xx.xx.xx.29 but not 30 or internet.  Makes no sence any ideas?

The wierd thing is if I set static xxx.xxx.xxx.30 to a nic and connect direct i can connect no problem.  So it is a rut with the rououting issue with the router for sure.

Not sure from your description, but are you doing NAT? If not, you won't get any response from a non-local public  IP address.

ok right i don't have nat setup as this router has changed config from local to internet gateway, how dumb i knew it was something small and NAT slipped my mind. As I am new to the CLI and since the question is worht 500 points what commands would I issue to resolve this.  Thanks again

So to better word this how can I set NAT to allow access by VLAN so for example I would like VLAN1 to be able to connect to xxx.xxx.xxx.29 through FastEthernet0 (xxx.xxx.xxx.30)
Don JohnstonInstructorCommented:
What type/model equipment are you using? Can you post your current config?
Don JohnstonInstructorCommented:
Absent that:

int x/x (whichever one is connected to your LAN)
 ip nat inside

int y/y (whichever one is connected to the internet)
 ip nat outside

ip nat inside source list 1 interface y/y
access-list 1 permit any
