netmask with qjail

[Sergei G]

I would like to control netmask in qjail environment and I can't figure out
how.

I looked quickly inside qjail script and all I see is that it does not
allow IP/mask format for IP address.  So, I am a bit lost.

The default mask reported by ifconfig inside jail is:

 inet 192.168.3.17 netmask 0xffffffff broadcast 192.168.3.17

I'd like it to be like netmask 0xffffff00


I am afraid that qjail simply does not allow netwmask as I can't find any
reference to it in documentation.
