Site-to-Site VPNs and VLANS

Hi,

We've run a flat lan for years at our main location.

We've recently updated our network and added a few new VLANS to the mix.

Now I have a problem.  We have several Site-to-Site VPNs up and running that work great with our original VLAN1.

However, when I try to add our new VLAN subnets into the VPN configuration, the tunnels go down and will not come back up.

I've added the new VLAN Subnets to the Rules and policies already.

Can't figure out what I'm missing.

  • If you have both the access you have to add local id remote id and vlan subnet on ipsec tunnel as well as you have to add on firewall rules to have communication 

    In your case first you add local and remote id and new vlan on local and remote subnet on both the firewall to make it work 

    exmaple 

    At HO

    local subnet                                     Remote subnet

    Headoffice LAN                                 Branch office LAN

    new VLAN subnet

    At BO

    local subnet                                 Remote subnet

    Branch office LAN                      Head office LAN 

                                                          New VLAN subnet
