Hello all!
All client machines of my costumer can´t load all itens in a web site. It load something like a half of all itens then stops. e.g.
www.csn.com.br
I tried to purge and disable caching and he tried to connect when all the other machines was turned off... no changes occured.
If I try to open the web site from WinGate server machine, no problems occur.
He is using WinGate 6.0.4 1025 with NAT.
Anyone knows what is happening?
Thanx for all,
Ricardo

Hi
Is this with all web sites?
What sort of internet connection is your client using? PPPoE?
If you look in the adapter properties in GateKeeper, what is showing for the MTU of the network adapters?

Hi Adrien
Just some web sites like "
http://www.csn.com.br" the problem happens.
My client has a dedicated link (1.2Mb) and MTU value is 1500 (Both NICs).

Do you know if the link uses PPPoE or has a reduced MTU?
Some links do, but the adapter still shows 1500 as the MTU of the adapter.
The best way to tell is to try to ping some site on the internet with large packets.
For instance if you run from the command line
ping somesite -f -l 1472
that will send a 1500 byte (1472 + 28 bytes for ICMP/IP header) packet and will set the "don't fragment" header.
If you get a successful reply back, then you know that your link doesn't have a reduced MTU. If you get something back like
"reply from someip packet needs fragmentation but DF set"
or a timeout when you can normally ping that site with a smaller packet (i.e. with just "ping somesite") then it is possible the link MTU is reduced.
You would then need to experiment with the size of the packets you can send, until you find the largest packet you can send. Add 28 and that is the MTU of your link, and that would be what you would need to set your adapter MTU to.

Hi Adrien,
His MTU is 1498. But after windows crash, his formatted the HD and all seems fine now.
Thanx for your help!
