one ISP 2 IP
-
Hello, is it possible to use from one ISP provider 2 ip on pfsense?
If yes. how to set up this? -
Like 2 WAN links or multiple public IPs on one WAN?

-
@stephenw10 So , understood that will work as VIP and should set on WAN in IP alias field?
-
Yes you would add it as a IPAlias VIP on the WAN. Firewall > Virtual IPs.
But that screenshot is from the dhcp client setup which is nothing to do with it.
-
@stephenw10 Ah, firewall - VIP. Did search with closed eyes)))
-
@stephenw10 This VIP should work like normal WAN IP. I mean regarding provider speed , latency and etc? Can pfBlockerNG filtering VIP? Can use pfSesne OpenVPN client on him? Like me understood IP Alias use all benefits as normal NAT.
-
Yes you can run services on it directly. You can add NAT rules to or from it for services or internal subnets.
Your ISP has to provide the IP(s) though of course.
-
@stephenw10 So, lets say will have 2 WAN IP and 3 additional NIC's. Can I use ona LAN for one WAN IP and the rest 2 for other WAN IP only? or can use on one LAN this 2 WAN IP for different types of traffic?

What are do you mean?
-
You can use the WAN IPs for whatever traffic you can match with outbound NAT rules. So that might be all traffic from an internal subnet. Or it could just be a single internal host.
Most ISPs will only provide you a single public IP unless you pay them to provide additional IPs. Actually using them does depend on how they provide it to you.

My ISP (Rogers) provides two. There are two Ethernet ports on the back of the modem and they have different addresses. I don't pay extra for it. I used to use the 2nd for testing, until a pfSense update broke that. There's a thread about that here somewhere.
-
@JKnott The same)))
My ISP provides also two IP. I still thinking, request or not second IP, because they will make second line in this case to my apartments and no any ideas for this moment how better to use this second IP or have benefits)))Speed will the same 1gb up/down. Could somebody provide some tips, how can use and for what second free IP?Subnet should be the same as my first IP, like me understanding better to use second pfSense interface as additional WAN, but it mean minus interface for my local subnets))) Still in doubt -
Is it a static IP? Second dhcp lease?
-
@stephenw10 Both have static IP. But for this moment use over DCHP on WAN. Is any benefits to set my first IP as static, because use DCHP lease on mY local subnets?

Mine are DHCP. For some reason, the MTU is smaller on the 2nd.
-
No there's no benefit and in fact there's a good chance your ISP still requires you to pull a lease even if it passes you the same IP every time.
If both IPs really are fixed then you should be able to just add the second IP as an IPAlias VIP on WAN and use it however you want.
-
@JKnott Can you set as static?and check MTU
pfSense plus 24.11 on Topton mini PC
CPU: Intel N100
NIC: Intel i-226v 4 pcs
RAM : 16 GB DDR5
Disk: 128 GB NVMe

Is it possible to check this on my side, without calling to ISP? Because I use as static and over DCHP and did not found any difference)))

20 YEARS , have the same IP))
-
Ha, well that's a long lease! The fact that it can use dhcp though implies the ISP could change it. They probably just default to the same IP unless there's a reason to change.
Are you spoofing the MAC address to keep that for 20yrs?
