IPFW and ACL-s
Hi,
i am running FreeBSD 4.9 and would like to setup a IPFW firewall. I would like to build my own ruleset, but i havent find anywhare if it is possible to build an ACL in that ruleset file.To have a list of IP-s for the later use in specific rules and in case anything changes, i dont have to change rules, i only add or remove some IP. For example: . . admin="192.0.0.100 192.0.0.105" users="192.0.0.150 192.0.0.151 192.0.0.152" . . add allow all from $admin to any add deny log all from $users to 209.247.228.201 . . Is it posible to do this in such way?

Create a shell script along the lines of:
Code:
#!/bin/sh # path to ipfw: ipfw=/sbin/ipfw admin="192.0.0.100 192.0.0.105" users="192.0.0.150 192.0.0.151 192.0.0.152" # then add the rules like: for adminip in $admin do $ipfw add allow all from $adminip to any done # similarly for users ... You can then load the firewall rules by executing the script.
