.SH CAVEATS
The ematch syntax uses '(' and ')' to group expressions. All braces need to be
# 'ipset(interactive src,src)'
+Check if packet matches an IPSec state with reqid 1:
+
+# 'ipt(-m policy --dir in --pol ipsec --reqid 1)'

.SH "AUTHOR"
The extended match infrastructure was added by Thomas Graf.

may be either
-.BR frag " or " nofrag
-to match on fragmented packets or not respectively.
+.BR frag ", " nofrag ", " firstfrag " or " nofirstfrag
+where frag and nofrag could be used to match on fragmented packets or not,
+respectively. firstfrag and nofirstfrag can be used to further distinguish
+fragmented packet. firstfrag can be used to indicate the first fragmented
+packet. nofirstfrag can be used to indicates subsequent fragmented packets
+or non-fragmented packets.

on the matches of the next lower layer. Precisely, layer one and two matches
