For example, if your TCP session negociates 1500 bytes as max frame       size but something in the middle is performing fragmentation (tunneling       over UDP, IPsec) then the remote firewall can suppress additionnal       fragment (ie linux ipfilter/iptables).              You can try to discriminate this behavior with a packet sniffer to see       if fragments are built and dropped by an equipment on the path.              Hope this helps.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
