That's correct. I wish being limited to only 100 Mb/s (65 Mb/s of IPsec VPN
[full packet size], according to the data sheet[1]) was a problem I needed
to work around. I assumed, perhaps incorrectly, that the requirement for
VPN implied a requirement for Internet.

Interesting. Let us know how you go with that.

but looks to be unsupported by the next Debian.  I'm hoping to replace a
managed 24-port gigabit ethernet switch with this and a 5W 8-port gigabit
switch, resulting in lower overall power consumption (and a *much* simpler

If you were looking at collapsing it all into a single device, then I would
understand why the 8-port 10/100 Mb/s switch inside the SRX110 would be
seen as a limitation.

Vaguely related: Last I picked up a pair of Supermicro E200-8D mini
servers. They're in a different league, price-wise, but they've been great.
In theory you could run a virtual instance of your favourite
router/firewall and, with AES-NI support, build a very high performance VPN
