Access to some sites may be VERY slow or doesn't work at all with different kinds of timeout messages or without messages at all (but other sites works fine). For example, firefox may say "Transferring data from..." message and then "The connection to the server was reset while the page was loading", lynx just says "HTTP/1.1 200 OK" and displays no data, etc. I'm also using Linux and Windows XP on the same machine, and the same sites are loaded very quickly. Note I'm not using a proxy. My NIC is: mskc0: port 0xc800-0xc8ff mem 0xcdefc000-0xcdefffff irq 17 at device 0.0 on pci2 msk0: on mskc0 msk0: Ethernet address: 00:11:2f:37:d5:19 miibus0: on msk0 e1000phy0: PHY 0 on miibus0 e1000phy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX-FDX, auto mskc0: [FILTER] And network configuration is: msk0: flags=8843 metric 0 mtu 1500 options=19a ether 00:11:2f:37:d5:19 inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255 media: Ethernet autoselect (100baseTX ) status: active lo0: flags=8049 metric 0 mtu 16384 inet 127.0.0.1 netmask 0xff000000 msk0 is DHCP-configured from Linux router, which is connected to ISP via PPPoE: eth0 Link encap:Ethernet HWaddr 00:01:C0:02:F5:45 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 ... eth1 Link encap:Ethernet HWaddr 00:01:C0:03:0A:66 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 ... ppp0 Link encap:Point-to-Point Protocol inet addr:X.X.X.X P-t-P:10.0.0.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1 ... Here eth0 is a "transport layer" for ppp0, which is connected to ISP, and eth1 is a local network interface. The Linux router does a full NAT for all machines from 192.168.1.0. I've tried to reduce MTU to match router's ppp0 setting with "ifconfig msk0 mtu 1492" and even down it to 1480, but it doesn't help. Any ideas ? Dmitry
