2 separate subnets from ISP

JimKoerner
We currently a subnet from our ISP that got filled up so they provided us with another separate subnet coming in on the same interface.

I am guessing I will need to setup a static gateway route to direct traffic out the provided gateway of the new subnet since it wont go through the default gateway which is in the original subnet.  I would then use DNAT/SNAT to get devices directed to the new subnet.  Does this sound right?  Never had a broken up range from an ISP before so looking from best practice on this.

Thanks,
              Jim Koerner

    Hi, Jim - interesting situation!

    Your solution sounds like the healthiest thing - Additional Addresses on the External interface with a gateway policy route like '{new subnet} -> Any -> Internet : via {new gateway}'.  Other than that, you should only need normal DNAT/SNATs as you're already using.

    Cheers - Bob
