we added a bt infinity connection and I need to add another vlan to our 4507R, but can't get it to work and I can't access it from another vlan.

this is what I've setup

!
vlan 40
 name BT Infinity
!

!
interface Vlan40
 description ----- BT Infinity - vlan 40 - 192.168.40.0/24 -----
 ip address 192.168.40.1 255.255.255.0
 ip helper-address 10.30.0.1
 no ip redirects
!

as part of sh ip route I can see:
C    192.168.40.0/24 is directly connected, Vlan40

from the 4507R i can ping the infinity router 192.168.40.254
#ping 192.168.40.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.40.254, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

but i can't ping it or open the admin page from any machine on vlan 1.

the bt infinity router is connected to a smaller switch, which is connected to interface GigabitEthernet6/11 on the 4507R and that has no access lists applied etc
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,40
