Support for IPOE, since it' s not only in use for consumer lines, but also for >100MB business lines, because lower overhead then pppoe.
Definitely, a customer of mine has received an offer for a free update from 100/100Mbps fiber WAN to 200/200Mbps.
The catch: 100/100 was PPPoE which works perfectly with a Sophos UTM, 200/200 is IPoE, which I am trying to figure out now how to do that.
A how-to guide would already be a good first step!
We also need this.
It looks like they aren't adding this functionality because it's still not marked.
