anyways, whatever, yes, you can do it with iptables, but not all off the shelf firewall script generators will support multiple LAN subnets. I usually write my own iptables rulesets.
I can say first hand that fwbuilder easily handles managing scripts for multiple subnets and aliased addressing on NIC's. I use separate interface cards for each subnet, however. (5 NIC's, 4 internal subnets, 3 public IP's on the one external facing NIC)
Hi Kevin, Expanding my original question. I have a need to open and close iptables rules based on particular time, say 1 week later, 1 month later, etc. Currently I have a simple script to do that:
- Create the rules.
- Create atd job to delete the rule based on the defined time.
- Log it.
It works, but not elegant :)
Does fwbuilder have that function?
Fwbuilder does indeed have time objects in it, although I have never used them.
The docs at http://fwbuilder.org are pretty extensive and the devs hang out on the mailing lists and regularly answer questions or provide pointers to the relevant docs.
Hope this helps.
