you already conducted a few non-VPN tests between direct-wire-connected laptops/devices at those two locations to know what "baseline" bandwidth you're starting from when considering the max potential bandwidth for the encrypted traffic? For example, since
you're on a business plan, you should have a direct public IP to target with iperf traffic from either end, even if not encrypted.<u></u><u></u></span></p>

<p class="MsoNormal">Hi, all.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">We've been trying to develop a plug-and-play L2 VPN over Starlink, using Aruba Hospitality-series Remote APs like their RAP-505H.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">It's not going great, and I'm wondering about several Starlink-specific issues.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">First, having multiple devices in serial is generally not a great idea for reliability. Can we realistically plug our remote AP directly into the dish, still? (This is using Starlink Business, FWIW.). I know we lose access to the Starlink
app, but we also lose a NATing router and an unwanted wifi AP, so that's probably a net zero. I just don't know what other dangers/problems that topology might cause.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">Secondly, we're only able to push about 30Mbps through the (magical Aruba-proprietary GRE+IPsec) tunnel. The bandwidth-delay equations suggest we should be seeing around 100Mbps, not 30. (The Aruba devices are rated for ~2Gbps encrypted
at the site end, and ~7Gbps at the head end, so presumably that's not the bottleneck.)<u></u><u></u></p>

<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">So:<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">* does anyone have corroborating *or* contradicting evidence of VPN performance over Starlink's particular flavor of Long Fat Pipe, and<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">* does anyone have any positive (or negative, I guess!) recommendations for cloud-managed VPN devices that can do at least 100M and magically work from behind double-NAT/CGNAT like we see with Starlink? Bonus points if it does L2 tunnels
or can run a dynamic routing protocol.<u></u><u></u></p>
