Re: [FW1] anti-spoofing on aliased interfaces





Lance

the virtual addresses do not show up in FW-1 interfaces screen

FW-1 ignores virtual interfaces, so anti-spoofing is performed on the
physical interface.    if you want to use virtual
interfaces with anti-spoofing, define 2 net objects (one for each subnet)
and create a group consisting of those objects.
then you can put the group in the physical interfaces anti-spoofing entry,
just as if there were another physical network
connected to the interface.

Subject:  [FW1] anti-spoofing on aliased interfaces





I've aliased an interface (hme0:1) on FW ver 4.1, running on Solaris.

Can one add an aliased interface to the interface objects
on a firewall?

Can one setup anti-spoofing on an aliased interface?

Last, does the aliased interface show up on the 'fw stat -li'
command?

Thanks!
