Hi,
I have a C887VA-k9 router.
I have interface Fa0 with VLAN 1000 connected to the LAN. It's subnet 192.168.1.0. I can ping the router from a PC from the LAN. The DHCP give an ip coming from the router.
I have interface Fa1 with VLAN 1 (default VLAN) with subnet 192.168.255.10 connected to the internet via a modem with IP 192.168.255.11. I can access the web from the router there is no problem with that.
Or i can't access the web from a PC in the LAN, it seem that there is no routing between the two subnet, VLAN or i did try to enable "ip routing" and it don't take it in the show conf below.
It will be easy without going throught vlan but if i try to put directy an ip address on Interface Fa1 i have "% IP addresses may not be configured on L2 links."
Below all information in details.
Can you help me, why i can't access the web from the PC ?
Thanks a lot

You may need to configure NAT on this router. Who controls the device at 192.168.255.11?

Thanks, yes apparently the problem was coming from missing NAT !
i have add :
Router(config)#interface vlan 1000
Router(config-if)# nat inside
Router(config)#interface vlan 1
Router(config-if)# nat outside
Router(config)#access-list 1 permit 192.168.1.0 0.0.0.255
Router(config)#ip nat inside source list 1 interface vlan 1 overload
And i have now the web from the PC.
Thanks a lof for your help
