[ILUG] [Q] Max number of TCP(?) packets without waiting for an ACK(?)

[Brian Foster]

 sorry if this doesn't make much sense, but I'm not
 too sure what I'm talking about ....  ;-\

  Kubuntu 7.04, fully up-to-date, 2.6.<2<something>>,
 with one (1) ethernet interface.

  the site sysadmin tells me the firewall (entering the
 DMZ, I presume) keeps complaining my workstation sends
 too many packets (TCP, I presume) without waiting for
 an ACK(?).  "too many" is somewhere north of c.250,
 which is the firewall's limit.

  does this make sense?

  perhaps rather more importantly, is there something
 I can set/tune/adjust to keep the maximum number of
 outstanding un-ACKed packets (or whatever) below a
 specified value.

  finally (this is mostly for my curiosity), is it
 possible to do so only for stuff routed into (or
 through) the DMZ?   i.e., for stuff which stays on
 the local intranet, everything seems to be working
 fine, so is it possible to not change the current
 behaviour (albeit the change is presumably benign?).

cheers!
