how to configure IPv4 static IP over OCN Hikari IPoE

[jeffersonchua]

I've followed the guide and the ER605 router is working fine, but it's getting different IP that what's NTT has assigned.

When I plugged in the Yamaha RTX1220 it's getting the correct static IP assigned by NTT, but when I use the ER605, it's getting a different IP. I've verified that with the newer TP-Link ER706W, I'm able to get the correct static IP assigned by NTT.

So, what's the steps to set for static WAN IP?

Thank you!

Hello @jeffersonchua, it's hard to understand exactly what is happening in your case. What interface is the ip assigned to? is it an ipv4 or ipv6? what is the length of the prefix you get on ipv6 with your ISP with the yamaha router? do the ipv4 / ipv6 you get with your ISP-provided router agree with the map-e calculator?

for example, if you have a plan that includes a voip line, you get a static ipv4 on wan, but that is specifically for voip, and not for general internet traffic. your yamaha router would also get this address assigned, but probably it would not be visible anywhere (since it's for the voip only), which may cause some confusion because it would look like you'd indeed get a different ipv4.
