Title: Interface alias VIPs and mask
Post by: fsebera on July 23, 2021, 08:11:41 PM
Should the fw interface alias VIPs use the same mask as the interface they are representing?

Example:
LAN IP 192.168.25.1
Mask 255.255.255.0 (or /24)

Alias VIP LAN IP 192.168.25.254 /24

Thank you
Frank

VIP means virtual. from that sense, you can just use 1.2.3.4/24 but what does that get ya?

you need to first ask what do you want to do with the VIP, and if that VIP represents another IP in the 192 subnet then yeah place it there.

Hi,

Yea I have tried different masks on the alias and all produce the same results - they all work.


Thanks
