But I don´t find anything for ASA</P><P></P><P></P><P><IMG src="https://community.cisco.com/" /></P> Tue, 12 Mar 2019 01:29:10 GMT dzimmi 2019-03-12T01:29:10Z LAND Attack https://community.cisco.com/t5/network-security/land-attack/m-p/2146828#M358124 <P>Hi Folks,</P><P></P><P>I try to launch a LAND Attack against my firewall ASA 5520.

I’m not surprise if your Cisco ASA is able to handle LAND ATTACKS well, which is a good news. The Cisco ASA receives a packet with the IP source address 127.0.0.1.</P><P></P><P style="text-align: justify;">There’s a another case on this, for your kind reference <A _jive_internal="true" href="https://community.cisco.com/thread/226294">https://supportforums.cisco.com/thread/226294</A></P></BODY></HTML> Wed, 24 Apr 2013 06:22:55 GMT https://community.cisco.com/t5/network-security/land-attack/m-p/2146829#M358125 Ramraj Sivagnanam Sivajanam 2013-04-24T06:22:55Z
