Hello,
I run a server with Astaro Security Gateway V 7.505 and i noticed that my internet speed is about 20 Mbps slower than it is supposed to be. My kind of internet contract is for 30 Mbps in download and as soon as the cable modem (Motorola Surfboard SB5101E) is connected to the server than my internet speed over the lan is just 10 Mbps (9.8 to be exact checked with speedtest.net). My first feeling was that there was something wrong with the network card. These are steps i followed:
Changed between 3 different NIC - All 3 supporting 10/100 Mbps, nothing changed
Checked the cable between the modem and the NIC on the server - OK, Cat 5e, the right one
Checked as far as i could via the GUI for possible bandwidth filters or limitations - didn't find any that i am aware of
Keeping in mind also that:
Connecting the laptop directly to the modem, resulted in the correct speed - so not an ISP related issue
The NIC that communicates with the modem is in auto-neogotiation by default and forcing it to 100 Mbps full-duplex didn't help
Internal LAN traffic over the other NIC runs fine at 100 Mbps.
I am out of ideas...so any suggestions or other checks that i could perform are more than wellcome.
Thanks
