"Adapter is in Passive Mode" Warning

Hi all, I was playing Snort rules and noticed the following doesn't work:
reject ICMP any any -> $HOME_NET any (msg:"Shut this rule off, it works now"; sid:100000;)
While
alert ICMP any any -> $HOME_NET any (msg:"Shut this rule off, it works now"; sid:100000;)
works fine. So I ran snort with -T flag and noticed:
WARNING: /usr/local/etc/snort/snort.conf(641) Adapter is in Passive Mode. Hence switching policy mode to tap.
Line 641 of snort.conf is where I tried to set policy to "inline" ("config policy_mode:inline"). Is there supposed to be a build flag to enable IPS capability on Snort? I looked at my FreeBSD ports option:
# make showconfig ===> The following configuration options are available for snort-2.9.4_1: BARNYARD=on: Depend on Barnyard2 DBGSNORT=off: Enable debugging symbols+core dumps FLEXRESP3=on: Enable flexible response on events (v3) GRE=on: Enable GRE support IPV6=on: IPv6 protocol LRGPCAP=off: Enable pcaps larger than 2GB MPLS=on: MPLS support NORMALIZER=on: Enable normalizer PERFPROFILE=on: Enable performance profiling PULLEDPORK=on: Depend on pulledpork REACT=on: Enable react SNORTSAM=off: Enable unofficial Snortsam patch SOURCEFIRE=on: Enable Sourcefire-specific build options TARGETBASED=on: Enable targetbased support ZLIB=on: Enable GZIP support
and couldn't seem to find any… Thanks!
