If your interface is configured for say 10.0.0.0/8, it will proxy arp for all the addresses that are part of this network. If you need to assign 2 IPs, make sure their subnets do not overlap.</P></BODY></HTML> Tue, 11 Sep 2012 13:28:25 GMT https://live.paloaltonetworks.com/t5/general-topics/second-ip-address/m-p/51344#M37760 zarina 2012-09-11T13:28:25Z
