Hello !
I'm using pfSense on a TEAK 3030 from ArinfoTek (Atom N270, 4 gigabits network
ports 82574L, http://www.arinfotek.com.tw/product.php?gid=1&pid=39).
Configuration :
ISP Modem ------ pfSense ------- Gigabit Switch----- LAN
pfSense WAN set by DHCP and doing NAT
ISP Modem network port is 100Mbit/s (pfSense see it as 100Mbit/s full
duplex)
LAN port is at 1000Mbit/s
The problem : It has worked for one month without any problem, before making
strange things :
- loosing internet connection
- no log at all when disconnection appears
- RDD graph "quality" showing 100% packet loss during the time of
disconnection
- RDD graph "traffic" showing some sent data but no data receive by WAN
interface
- Wan connection may come back by itself, but it cut again 10mn later
(or less)
- The lan interface stay up with no problem
- Making any change on network related option (DHCP Renew lease,
checksum option...etc), bring the connection back for a short time
- The problem seems to happen only when there is load on WAN (the
router doesn't disconnect at all during night)
- No ping response from the ISP Gateway (by the pfSense diagnostic page)
What i've already try, without any succes :
- disabling checksum hardware offload
- reducing MTU to 1492
- put WAN interface with static address (instead of DHCP)
- put the NAT in manual mode with static port
- change the wire between pfsense and ISP Box
Please, do you have any idea ? i'm going crazy !
Sebastian
PS : i've not been able to redo the problem unless putting the pfSense in
production, so for the moment i can do test only at night
PS 2 : sorry for my poor english....
