Subnet routed over p2p IP + carp

marcin20pl

Hello,

I have question how to config such thing:

ISP gw ip 1.x.x.1/30
my p2p ISP assinged IP: 1.x.x.2/30
my public assinged IPs: 2.x.x.x/26

My ISP is routing my public subnet (2.x.x.x/26) to ISP assinged IP (1.x.x.2/30) i want to setup two pfsense box with CARP and pfsync.

what i want to setup:

i want to use in "internal servers network" private ips from 192.168.x.x/24 network, and do the 1:1 NAT on pfsense box.

is it possible? and how to setup that?

thx lot.

It is possible. Since your subnet should be routed to you, you don't need proxy ARP. Add them under Virtual IP as type "other", then you can configure the 1:1 NAT as you desire.

Yes I already know that, it is working now with configuration of one pfsense, i'm wondering how to configure everything to be working with CARP failover etc..

now i have 1.x.x.2/30 as my WAN address and my public network assinged as other VIPs, then i'm doing 1:1 NAT.

and now how to add 2-nd pfsense box? what ip should i use as WAN address on each pfsense? what ip should i use as WAN CARP ip? can i still use private IPs 192.168.x.x inside my LAN?

edit:
realy? noone knows? :(
