MultiWAN on DHCP assigned ip addresses

[Robin]

Hello all

I am new here on the forum, but know my way around Networks.

I have a fairly difficult problem to solve.

Basically my ISP only allows trafic on interfaces that has successfully requested an address by means of dhcp.

and I subscribe for 5 ips, which naturally means I have 5 ips that I can reserve (all public ofcourse).

my problem is this, all of these ips are on the same subnet, but I wish to use them on my pfsense, and then let pfsense handle what traffic goes where.

is there no way I can achieve this with my current isp?

best regards.
Robin

I'm attempting to complete the same setup and from what I've gathered as long as these IPs share the same gateway we're going to run in to issues :\

Some suggestions I've seen including putting one WAN on an old Linksys DMZ for the NAT.

Yes I did something similar, but I am very unhappy with the setup.

twice times nat, just dont sit well with me

This is possible with 1:1 NATing.

I have a /29 range of IP addresses but they're static.  If you're going to get the same range of 5 public IP addresses from your ISP you should be fine.  If not there's no practical way to re-map a new address range to the routes you've already established.
