Broadcast Address Usage in NAT

[ammartalal]

We have a customer who is connected with a /30 (point-to-point) address, interface at our side is having IP 192.168.7.65 255.255.255.252, and at their side is 192.168.7.66 255.255.255.252

The customer wants to use the IP address 192.168.7.67 (the broadcast address) for NATing on the router, and they claim it was working with them before but is not working now.

Is it possible for them to use the broadcast address for normal traffic?

I do not believe nor I am aware that it works with that Address as claimed here.....Maybe it was a different subnet more than /30 before.(chances customer may be confused)

by the way, is the same setup or upgraded ? as you mentioned only 65 and 66 were usable.

No it is not, not even for NAT
