Bridging Issue

Hey Guys,

 

First time I am setting up bridging on my 887. I have done some research and looked at some solutions online although I have not had any luck sorting this one out. I have plugged my wireless router (which is assigning via dhcp) into fe0 assigned to vlan 100. clients on vlan 2 assigned to fe1/3. Not having any luck seeing the internet off vlan 2.

 

any help would be appreciated!

Some help would be great... :)

You shouldn't assign IP to  VLAN100 interface. The address is allocated to BVI interface.

New output

" interface Vlan100
 description bridging interface
 no ip address
 ip nat outside
 ip virtual-reassembly in
 ip tcp adjust-mss 1452
 bridge-group 100

 

interface BVI100
ip address 192.168.254.1 255.255.255.0

Hi quatreduros,

 

Thanks for the feedback. Unfortunately I still cannot see the internet router from the cisco vlan 2.

 

EDIT: Do I need to set the BVI's subnet to the subnet that of the other wireless router?

 

Say my wireless router is 192.168.111.1 and has DHCP running on it, do I set the BVI to 192.168.111.x? Or do I allow the BVI to grab an address from DHCP?

 

I have used dhcp on the bvi interface. I can now see the internet from the Cisco, but I might have a NAT problem? Still no internet on vlan 2.

 

Thanks mate!
