5 firewalls to 1



  • Hi everyone,

    This is a VMWare setup - I didn't create it, it just is and I would like to tidy it up if possible.
    My understanding is limited but I think I should be able to work through this logically and get the result I'm after.

    I currently have 5 subnets connecting to 5 firewalls through 11 IP addresses

    Can I a) take these 5 and and turn it into 1 firewall to rule them all
    if so b) what is the best way to approach this. Would it be best to assign an interface to each of the IP addresses below then use the interface groups to effectively re create in 1 firewall the 5 firewalls. Or could I assign an interface to each of the subnets then let the firewall do the work.
    or something else entirely.

    Thank you for any help you may be able to provide.

    INT 1-4 and EXT 1 represent vmware switch networks. INT is internal EXT is external.
