    This is related to the solved thread at:

    https://www-secure.symantec.com/connect/forums/quick-custom-ips-assist-please

    where thatdude helped solve the immediate issue.

    Now a new issue has cropped up in the SAME area.  Thanks to the great FAST help in the above thread, I was able to allow a computer access to a specific site that was otherwise blocked. NOW, I need to allow access to multiple computers  - 4 of them in total. Not a whole IP range, and in fact, 2 of the computers are on one subnet, 2 are on another.
    I know/understand I can allow a range by doing rule tcp, dest=(80,443), saddr=(123.456.789.32/27), msg="Allow Facebook",content="facebook.com" and allow all of the PCs in the 123.456.789.32 subnet access using that rule BELOW the block rule.

    CAN I DO THIS:

    rule tcp, dest=(80,443), saddr=(111.222.333.97/32,111.222.333.99/32,111.222.111.91/32,111.222.111.93/32), msg="Allow Facebook",content="facebook.com"

    and allow 4 computers, each with a different IP address?

    OR, must I create a rule for each? And how would THAT work out?

    I BLOCK facebook access with THIS rule:

    rule tcp, dest=(80,443), msg="Facebook Not Allowed",content="facebook.com"

    I need an allow rule for 4 computers, 4 different IP addresses (persistant IPs, they will not change)

    Thanks!!!!!!!!!!!!!!
