4402 Wireless Controller (p1 to 24P G0/2)
3560- 24 port POE (G0/1 to 48P G0/2)
3560-48Port (G0/1 to 1841 F0/0)
Cisco 1841 router (F0/1 to core net)
The 4402 uses 3 dot1q vlans. I want to use the 1841 to route between the vlans as the 1841 has a firewall which is a requirement that must be used in this design. I thought I could use dot1q on the gi0/x interfaces up to the router and then utilize the firewall on the router to route traffic between the VLANS. I configured the wireless network without the router and everything works fine. I remove all the int vlan entries, install the dot1q encapsulation on the G0/x ints, create the 1841 subinterfaces and NO GO. I could be way off base on how I think this should work and since it DOESN'T work I'm looking forward to any assistance you can provide.
3560 Switches
48 port - G0/1 and G0/2
switchport trunk encapsulation dot1q
switchport mode dynamic desirable
24 port -
g0/1
switchport trunk encapsulation dot1q
switchport mode dynamic desirable
g0/2 Wireless 4402
switchport trunk encapsulation dot1q
switchport mode trunk
Cisco 1840 with K9-Sec Image
created sub intefaces on 1841 int f0/0
assigned dot1q vlan to each sub int
assigned ip address to each sub int
Example:
int f0/0.5
encaspulation dot1Q 3
ip address 172.31.115.1 255.255.255.0
ip helper-address 172.29.115.1
When I run a trace on the 24P G0/2 I can see an arp request go out when I attempt to ping from the wireless controller console and thats it. Your help is greatly appreciated!
Note: I have attached the configs for your viewing pleasure.
Thanks,
Scott

Hey there Scott,
As a test, create 2 vlans on the switch, don't have it routing and connect it to the 1841.
Put a PC in each of the vlans and get a ping going, using the 1841 for intervlan routing.
Then build it up from there.
Let me know how it goes!
Regards,
LH
