I would imagine the answer to this is yes, but I haven't found anything on
the subject. If you wanted to limit outbound traffic for a certain port to
certain group of servers is that possible?
For example, can I create a group:
MAILSERVERS = 192.168.0.25, 192.168.0.26, 192.168.0.27
and use that in a ruleset:
-A INSIDE_ACCESS_OUT -s $MAILSERVERS -p tcp -m tcp --dport 25 --tcp-flags
SYN,RST,ACK SYN -j ACCEPT
and then drop the rest:
-A INSIDE_ACCESS_OUT -p tcp -m tcp --dport 25 -j DROP
