Have you tried to put it into a variable? Like so:
trusted="{ 192.168.1.0/24 or 192.168.2.0/24 }"
Then subsequently, change your rule as follows:
> ***00105 0 0 allow tcp from 192.168.1.0/24,192.168.2.0/24 to any
> dst-port 21,25,80,110,443,995 via xl0,rl0 setup keep-state***
... tcp from $trusted to any dst-port 21,25,80 etc
This is the way I've always done it, and I've never tried it yours, so
I don't have an answer to why it does not work. I've just stuck what
does ;o)
HTH,
Steve
