alt Hacker NewsIPv6 support is basic at best. The zone-based firewall is very prescriptive and limited. ACL stuff is not great. To increase the MTU of the physical interface connected to the ISP I would need to hack a systemd unit that did it on boot (I either need it at 1508 so the PPPoE interface uses 1500, or I need to MSS clamp it and have it effectively reduced to 1492). Initial configuration requires the device to be connected to the Internet.
There were a few other niggles, and in the end I just found it easier to do what I need on OpenWRT.

just genuinely curious about your MTU use case and why this is required...?

The MTU thing is a bit bizarre - all connections I've seen on PPPoE in practice (fiber or DSL) used 1492 MTU to fit data into frames (and ISPs configured their routers like that too). What are you trying to hack with this unusual 1508 frame size?
