I need to allow traffic through TCP/1494 and TCP/2598 (inbound & outbound) to IP range 10.1.25.1 to 10.1.25.254 within a Cisco ASA 5505.

Can someone please help me with this?

Under Cisco ADSM 6.0 for ASA I can add a network object with one IP address, but not a range.

Add Network Object

Thanks!

Select something else than "host" when creating a network object.

Examples (from ASDM 7.1, but it's the same for ASDM 6)

Add Network Object as a different type

enter image description here

Notice that I added a network with a /24 bit (255.255.255.0) netmask instead of a range, since you already wanted to specify a full subnet. You could select range instead if you want to, but in this case it's much cleaner to use a subnet mask.

  • Unfortunately I don't have this option for Type, probably due to the old software / firmware (I just added a screenshot to the original post). I think this network object needs to be added via the command line perhaps, I'm just not sure how.

  • You do have the same type, you just have to use a different netmask. 255.255.255.0 is /24 bit (as in .1 to 254), 255.255.255.255 is /32 bit (a single host) etc. Just learn subneting and you're fine.
