Hi all,

in the eternal mistery of this topic with no help or support from the
the firewall (as default internet gateway) with Intermediary section
values of default

Assemble packets: ON
MTU: 1500
MSS Auto Adjust: disabled

if you do a speed test it say you have a 20Megabit connection while you
have a 100Mb FTTC

playing with these parameters the situation improve
(e.g. giving 1492 as MTU and playing with MSS)

on an FTTC (100Mbit/sec full granted) i'm able even to raise downloads
from 2 MegaBytes/sec to 9MegaBytes/sec, anyway the upstreaming bandwidth
it's not
so much good and i'd like to improve it

even using tcp analyzer

i'm not able to improve further the performances (download/upload datarate)
and i get no support at all from the sw house, ticket not answered etc...

Has this simply not been a long standing issue that the performance of the Injoy firewall, where the systems is connected to a fast internet connections lags behind ?

playin with RWIN size in inetcfg.ini it seems not to improve too much

while i can survive with this in my office, i still have aound some
Injoy FW
at customers's places and internet speed improvement is giving me some

anyone has experience with IJ FW and a 100Megabit/sec FTTC connection
using INJOY FW as default lan gateway?

I am starting to get the impression this is a a current, please note thst word *current*, limitation in fxwrap.sys.
