Multi Subnet/WAN from multi ISP to single interface
-
Right now I am using unmanaged switch to distribute Public IP from 2 ISP ( each have /28 network ).
The IPs are being used for some directly connected servers,
and to 2 pfsense nat boxes ( physically attached nic to the switch )I know it may not be a good practice, but to my surprise the unmanaged switch works.
If I put ip addr add ( along with the additional routing table ) on any of the linux servers,
they have 2 diff IP from 2 diff. ISP.Now on the pfsense nat box, how do i achieve this ?
I knew i can put additional IP in CARP virtual interface, but they're in the same subnet and same gateway from 1 ISP.
Will I be able to just add ISP2 Gateway, and add ISP2 public IP to this single WAN interface as virtual IP / CARP in pfsense ?The reason is there will be third ISP coming in.. And I think having additional pfsense is not quite practical.

If you don't have enough network ports on pfSense consider to get a VLAN capable switch and assign both WANs as VLANs to pfSense. -
Yes... thought so .. Guess it will have to come to that after all...
Thanks !
