Sify's newest bband client ( 2.8 ) can block ports on windows 2000 and xp using the windows inbuilt ipsec policies (without ur permission ) .
C:\ program files\sify broadband folder contains 3-4 files showing this
1) ipseccmd.exe ( to install policies )
Ipsecutil.dll
ipsecpol.exe
text2pol.dll
now the new bband client downloads rules file from sify server and install it on ur pc pc and so by this sify can block ur ports anytime right from ur own pc .. (works on 2k/xp) .
To check what all ports are blocked for you:
start-->run-->secpol.msc
see Ip security policies
then there will be a policy named FILter showing Assigned tab as YES in front of it and u can see what all ports is sify blocking on ur pc ..
