I browse from a LAN made up of 80 workstations and have a very capable internet connection but from some days ago, I am experiencing enormous delays to download/upload files for some reason.
My connection config is as follows:
ISA Server (web proxy, gfi webmonitor),edge firewall model (two NIC's, whereas one is LAN and the other the INTERNET);
In a separate computer, I have my LAN server which is the PDC as well as DNS and DHCP "patron";
No client makes a direct connection to 'outside'.
I have connected directly to my router to see whether the problem was from my ISP but the connection speed seemed normal and could even download big files without delays. For e.g. a 65Mb file, connecting directly was downloaded at 250Kb/s, while repeating the procedure passing through the normal configs. it could not go higher than 4Kb/s!!!
I have included snapshots of my ISA firewall policies in case I have my orders wrong.
