CIDR support on ASA

[Roberto Kippins]

Hi I got got two new ASA 5508-X. The software version is 9.5.1 and ASDM is 7.5.1. Previously on my ASA 5505's I was allowed to add addresses like 10.100.0.0 /16 in any of my configurations, now the new ASA's are telling me I cant use that, but I want to allow that block of addresses through a vpn and add it to some nat configurations. So far it seems like I need to add each network manually but that is a pain. Any suggestions.

Hi Roberto,

Are you trying to use "/"  in the object definition.

In case you are using it then use then subnet mask to represent the address.

For eg: instead of 10.0.1.0/24 , use 10.0.1.0 255.255.255.0

Hope it helps.

Thanks,

AO
