Note that it's rather important that your router does not reorder packets; I think UHD for
the most of its existence wasn't able to put incorrectly ordered packets back, and even if
it can, it comes with an inherent latency and CPU load – both things you need to avoid.
Also: You might have a gigabit Internet line, but don't forget that even a mediocre 10
MS/s stream from your USRP means a *constant* load of 320 Mb/s. I know no residential ISP
who would guarantee that for any duration of time! University/Research institute access
might be different, but even then, you would probably want to give your network operation
team a bit of a heads up and let them have input on your problem; it's thoroughly possible
that you end up getting a NAT-free VLAN connecting the two ends of your experiment if your
uni's team is as cool as mine.
Best regards,

I have an X300 and N210 I’d like to access through my firewall via a UHD based app. Is
this possible, and which port should I forward?
Thanks,

We don't recommend using USRPs through routers -- they have a de-minimis IP routing
stack in them, and should be thought
of more as a hardware device that happens to use ethernet as a "device bus" than a
first-class IP host.
There are also both performance and reliability issues--the protocols used are UDP
based, and they don't have any
retransmit capability, so cannot handle packet-loss that is inevitable on multi-hop
routed connections.
That said, the UDP ports involved at 49152 and 49153 as I recall.
