That's certainly an option, although I was hoping to avoid having to have an extra device and extra power brick. > With a router you also usually get better antennas, (and the option to use > external antennas).

My assumption is that I will get mediocre connectivity (in terms of IPv6 or no IPv6, etc.) from a mobile provider, and I plan to get proper connectivity with static IP4 and IPv6 by tunnelling across the cellular link. > We've done detailed write-ups about using LTE bridges with OpenBSD on our > research site, by the way. Thanks, found it, will take a look. Alex
