How Bind more ip in one NIC?

cmb

That's not possible with any OS. The usual way to pull multiple DHCP IPs is multiple NICs.

Ermal had an idea about using additional virtual netgraph interfaces but it would take quite a bit of development to make that work.

why ? I using windows 2008 can add multiple ip in one NIC. why PF can't do it? and ISP how bind ips for MAC?

You can have multiple IPs per nic with static IPs, yes (IP Alias VIPs) but not all via DHCP.

It's just not possible in FreeBSD yet without some extra work (like I mentioned, maybe virtual netgraph interfaces, or multiple physical NICs, etc)

I can't add it in static mapping now.

This Hostname, IP or MAC address already exists.

I search about some informations.

The DHCP server has nothing to do with the DHCP client.

The links you show are for multiple static IPs, not DHCP. This is already possible using "IP Alias" type Virtual IPs (Firewall > Virtual IPs).

ok. but how I setup ip bind to NIC MAC? So that use ARP Table Static.

jimp

static ARP has nothing to do with binding IPs to an adapter, and should be a topic for a new thread.

I mean is need setup Static ip for clients server,some clients computer must need some ips. So I have to bind some ips to they computer MAC.

jimp

That is not called binding an IP, that is simply called static ARP. You do not assign or bind such IPs to NICs on the firewall. Static ARP creates, as the name implies, a static ARP entry that associates a specific MAC address with a specific IP address on a client system.

If you try to bind a client IP on the firewall, you'll create an IP conflict.

Please create a new topic if you want to discuss static ARP.
