Model: TL-ER5120  
Hardware Version:
Firmware Version: 4

Hi, has anyone worked out how to use a /31 IP address on these routers?

 

I have a /31  1 ip for my router and 1 ip for the gateway.  on /31 there is no broadcast or network address but it seems the 5120 does not have any support for adding a /31.  If I try and add it, it refuses to take the IP as it says this is a Broadcast or Network address.

 

regards

ER5120 doesn't support /31 IP address. If your ISP provide the /31 IP address, maybe you need to use other routers to replace ER5120 for network access.
