in my current scenario, I have 4 interfaces configured with different Public IP address and each interface linked to the different router and each interface have different services (Internet Email1, Email2, VPN)
Our Plan to get a new line from a new ISP, in these case, we got only one router and the old Routers we canceled and we will get 6 Public IP address My Question :
1- How I configure the 4 interfaces to one router
2- required configure subinterface
3- what is the requirement for complete this project
Why are you using separate ports for each service? This seems to be an extreme waste of ports. Why not just use a single port on the PAN and create subinterfaces for each service if you are going to separate them that way?
ISP <---> Router <---> PAN (subinterface 1,2,3,4)
I have 6 ISP's with up to 62 ip's each.
I have used subinterfaces.
you add first IP to layer 3 port and in advanced, tick "untagged subinterface"
select the interface and at the bottom of the page you can add subinterface.
give it a unique number (I use the last octet of the address as a reference) and add it to it's own zone.
not everyones cup of tea but works for me...
add one ip address to interface 1/1 and go to advanced and tick the box for "untagged subinterface"
then select the interface again and the option to add a subinterface is at the bottom of the page
