well if you're not getting very good throughput on typical transfers,
like downloads or what not, I'd start looking for performance issues. 
First and most common is a duplex mismatch.  from there, I'd start
looking at logs and other things.  Doesn't sound like performance is a
problem in general though, or else your RDP over VPN wouldn't work
well.

I wouldn't have added any rules, the default is fine.

No, ICA uses TCP 1494 unless you've specifically changed that, or
you're running over the web interface.

That actually to or from your Citrix server?  Looks like something
that got cut off from the state table before the connection was really
closed.  shouldn't be a problem though, it happens periodically.
