Double /30 for wan
I got a specific question regarding a specific design.
I wnt to share a fiber connection between two companies.
My isp give me two /30 subnet and ask i got this specific design:
I need to have one specific router on first /30 and a second one with second /30.
I implemented a pfsense as router 1 and all entry trafic is correct but i got one issue regarding existing trafic for second subnet.
Indeed the design i understood is to connect fiber RAD to pfsense as igb1 (wan) then i implemented igb 1 as LAN1 and IGB 2 as second subnet /30.
For first lan implemented on igb1 all is ok.
For second one all renty trafic is ok but when i perfomr a myip.com query i got the wrong public IP.
Can i force second LAn to not NAT trafic to first /30 but still second one regarding that second /30 is public ip?????
I hope my query is clear if not don't hesitate to ask for more.....
Finally i solve it myself using this link https://docs.netgate.com/pfsense/en/latest/interfaces/using-public-ip-addresses-on-an-interface.html
The idea is to not ANT second /subnet as it s already an Public IP subnet.
