Ping BT HomeHub fails CCNA

[Tricky]

All,

Messing about with CCNA Lab and have the following:

BT HH - 192.168.100.254
R1 F0/0 192.168.100.1 (Cisco 1841 Router)
R1 F0/1 10.1.11.1
S1 F0/8 10.1.11.11 (VLAN1 - Cisco 2900XL Switch)

PC 192.168.100.123

Gateway of Last Resort is 192.168.100.254 on R1

From R1 I can Ping every device on the network as above including others on 192.168.100.x

From S1 I can ping every device on the network EXCEPT 192.168.100.254 including many others on 192.168.100.x

HH <--> R1 <--> S1 is all hardwired...

Been pulling my hair out and cannot work it out .. any ideas/help?

The Homehub has no specific route to 10.0.0.0/8 and is using its default gateway which will be WAN side, simples.

Try a ping from R1 specifying a source interface of Fe0/1 and that too will fail.

Doh quite obvious really ... o well time to dump the HomeHub and replace with a Cisco 857W
No easy way of putting a static or any other route back from HomeHub

Cheers mate - You were right by the way simple test from fa0/1 proved zero response...

No worries, you'd hope with the amount of time I've worked with this stuff I wouldn't miss the obvious too often!

Knew I could break it ... Couldn't add a route on HomeHub so made R1 a NAT

0/0 = Outside
0/1 = Inside

ip nat pool WAN 192.168.100.1 192.168.100.1 netmask 255.255.255.0
access-list 10 permit 10.1.11.0 0.0.0.255
ip nat inside source list 10 pool WAN overload
ip route 0.0.0.0 0.0.0.0 fastethernet 0/0

And it works
