Multiple IP/Subnets on WAN physical interface

Hi Alessandro,

You may consider to take look at the alias which binds different ip to the interface.

Hi Vadym, 

yes, I considered the alias, but with alias I can't set the default gateway for the second range of IP so it's unusable.

Then you have only two options VLAN or separate Physically.

So we can separate the WAN interfaces physically with the firewall in gateway mode?  I have 2 routers that have their own public ip that use the public ip of the firewall as the gateway.

Alessandro,

Alias are used to add additional ip on the same physical interface belonging to the same network and having the same gateway as the first ip configured on the physical interface.

The option proposed by Vadym are the only solutions.
