Can't mess with IP tables on the server. Well I could but that would
require a week of paperwork ;)

Something like match ip src 10.208.208.0/21 match ip should work in tc but
how do I say not port? I know I can say sport but not sure about port and I
have no idea how to say "not port"

as for latency range delay takes 2 arguments so it would be netem delay
100ms 150ms would be from 100ms-250ms delay. IIRC

Also you are using outbound/root, which I know is more full featured.
Trying to get something to work on inbound... I think I may just be too
tired and should probably call it a day and try tomorrow... Unless an
expert show up with a magic pill for me so I don't have to think at 7am :)
