Will this vlan work?

[dbar]

I have two sites, each with their own internet connection, but connected to each other wirelessly. I want site B to be able to use the site A internet connection using a seperate public IP address. Essentially I'm looking for a backup internet connection in case the internet at site B goes down (which it does often). What makes me unsure of the config is that there is already a "wireless" vlan in place. The wireless network is essentially an access point at site A that serves about 3 other sites.

Internet connection for site B would be in port 2

Site "A" switch

vlan 1
   name "sitea"
   untagged 3-28
   ip address 192.168.71.7 255.255.255.0
   no untagged 1
   exit
vlan 2
   name "wireless"
   untagged 1
   ip address 192.168.70.1 255.255.255.0
   exit

vlan 3

   name "sitebinternet"

   tagged 2
   ip adress 192.168.72.1 255.255.255.0

   exit

Site "B" switch

vlan 1
   name "siteb"
   untagged 1-20,25-28
   ip address 172.22.24.41 255.255.255.0
   no untagged 23-24
   exit
vlan 3
   name "sitebinternet"
   tagged 23-24
   ip address 192.168.72.2 255.255.255.0
   exit

Would this allow me to connect the Site B wireless link to port 23, then the firwall to port 24 and then use the public ip address on the firewall?

Hi dbar,

Will this vlan work? => Probably Yes. But you need to check if you Switch accept the routing, and this routing is activated by the command 'ip routing'.
