Cisco 4507R toubleshoot accessing 192.168.40.254 on vlan 40 from vlan 1
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
name BT Infinity
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
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
