/32 DHCP

[Anime4000]

I testing my 4G Backup for my Fiber Line.

I got DHCP /32 from ISP when I make bridge connection in order to reduce NAT point,

 

It's possible to duplicate ISP setup in other LAN environment?

What is the advantage/disadvantage using /32 subnet?

No idea what you mean with that. You need to word your question better.

It's one, single IP-address.

I mean to replicate /32 DHCP in office networking, what I read, this pretty common for PPPoE (L3)

/32 is literally a single IP-address, it would be of zero use in an office-setting for multiple PCs, unless you want NAT.

 

If I understand correctly what you're trying to achieve, you'd need to:

1. Configure the 4G-modem as a bridge.
2. Set up a firewall and connect the modem to it.
3. Connect the firewall to a switch.
4. Connect any PCs you want to have Internet-connection over 4G to the switch.

A lot of routers allow plugging the USB 4G adapter in a USB port and handle failover automatically.
