For IPv4 port forwarding, you would use http://10.31.33.7/fwd to add/remove forwards. For IPv6, the URL is http://[2001:db8::7]/fwd We couldn't figure out a way to do both IPv6 and IPv4 using the pre-existing http://10.31.33.7/fwd, at least not without changing a lot of things, and potentially breaking stuff for people who might not want to use IPv6.
