<div dir="auto"></div>
<div dir="auto" style="">Ok, yeah, that radically changes the situation. Also, we're not getting static or predictable IPs. I can follow that up, anyway, thanks!</div>

Interesting scenario. This reply only addresses a small part of your message: While I see you've done the math and checked the specs for the Aruba devices -- have 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.</div>

<div dir="auto">Hi, all.</div>
<div dir="auto">We've been trying to develop a plug-and-play L2 VPN over Starlink, using Aruba Hospitality-series Remote APs like their RAP-505H.</div>
<div dir="auto">It's not going great, and I'm wondering about several Starlink-specific issues.</div>
<div dir="auto"><br>
</div>
<div dir="auto">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.</div>
<div dir="auto"><br>
</div>
<div dir="auto">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.)</div>
<div dir="auto"></div>
<div id="x_m_5417424941266097326m_6961121106673671900ms-outlook-mobile-signature" dir="auto">
<div><br>
</div>
<div dir="auto">So:</div>
<div dir="auto">* does anyone have corroborating *or* contradicting evidence of VPN performance over Starlink's particular flavor of Long Fat Pipe, and</div>
<div dir="auto">* 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.</div>
<div dir="auto">* Other comments or suggestions welcome, too.</div>
<div dir="auto"><br>

<div dir="auto">Thanks,</div>
