All flavors of cisco routers I know of will reject arp updates like this from a MS server running NLB.</P><P></P><P>My question is will MS NLB unicast still work on ASA's running 7/8 code? </P><P></P><P>Thanks.</P> Wed, 13 Mar 2019 00:52:45 GMT https://community.cisco.com/t5/network-security/ms-nlb-on-asa/m-p/821208#M958324 ggonsoulin 2019-03-13T00:52:45Z Re: MS NLB on ASA https://community.cisco.com/t5/network-security/ms-nlb-on-asa/m-p/821209#M958325 <HTML><HEAD></HEAD><BODY><P>The ASA is similar to a Cisco router in terms of ARP operation.
