I get a strange problem here. We got another subnet from our ISP because we needed another block of IPs. Everything works fine, except one thing:
Deny IP spoof from (XXX.XXX.XXX.XXX) to XXX.XXX.XXX.XXX on interface outside
The source IP is our main IP from our primary subnet and the destination is one of the IP in the new subnet. Do I need to add a special rule to allow this trafic??
