Is there an extension that can check for values in the TCP/UDP payload ?

[刘伟鹏]

Hi,

 Recently I have studied the iptables which is used in linux, there
is an extension matche named u32_patch, which can check for values in
the TCP/UDP payload of a packet, and then decide whether let the
packet pass or block。

 I want to know how can I do this by using IpFilter on solaris 10u4?

 Looking forward to your reply,thanks。
