Also, tc doesn't support port-specific operations as that's all handled in a different space of the kernel.  Only iptables can do port-specific traffic shaping.  You'd have to do something really clever like direct all non port 22 traffic from specified ip to a tap interface off of a bridge and then use tc on that interface, but if you can't mess with iptables without lots of paperwork, I imagine making virtual network adapters public is also not a possibility.

well, for that, then it's a:

match ip src/dst 10.208.208.0/21

appended onto your tc.

To emulate loss, you'd use netem as well and just append a loss 1% to the end.

Lastly, to get a proper range you'd want to change delay 100ms to the average and then the range, so like:
delay 175ms 75ms loss 1%

It's all in the same tc module, so man tc-netem will be a lot more helpful than me.

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 :)

tc qdisc add dev eth0 root netem delay 100ms
iptables -A INPUT -m statistic --mode random --probability 0.01 -j DROP

That should get you started

I am looking for a tc command that will add 100-250ms of latency 

to all traffic that is not on port 22 

to/from an ip range like 10.208.208.0/21.

Bonus:

I would also like 0-1% packet loss

I would like this on inbound (ingress) not outbound (root) traffic

Any one able to help?
