Which provider you are using? NTT has many different providers. And for the ISP provided router, are you able to login and check the details?

It's NTT direct business line. I'm using the ER605 openwrt. Now I'm able to connect to the internet but can't figure out the value for EALEN, PSIDLEN and OFFSET, and my port ranges becuase the http://ipv4.web.fc2.com/map-e.html doesn't work

it should be OCN. you might be able to use v6mig to retrieve the parameters
