Hi all,
As the title says I have two Subnets 72(LAN) and 73(Wireless) and currently they can talk to each other. I.E, 73 Subnet can ping 72 etc etc.
Have only one router straight to one switch. Using Two Physical ports on the Router for each Subnet...
Is this an easy fix or do I need to start over to get this right?
Below is the config (Ive taken out the crud that isn't important) Ignore VLAN3 (Just playing with some Video Equipment)
no ip source-route

Try adding this to the config
These acess lists should block Vlan1 <----> Vlan 2
!
access-list 172 deny ip 192.168.72.0 0.0.0.255 192.168.73.0 0.0.0.255
access-list 172 permit ip any any
!
access-list 173 deny ip 192.168.73.0 0.0.0.255 192.168.72.0 0.0.0.255
access-list 173 permit ip any any
!
int vlan 1
