Please see http://www.shorewall.net/Shorewall_and_Aliased_Interfaces.html It is indeed unfortunate that additional addresses on an interface were ever made to look like additional interfaces -- there is no end to the confusion that has caused over the years. With static IP addresses, I suspect that you can do what you want fairly easily with arptables. But I also suspect that the one-IP/one-MAC restriction that you are mentioning would only apply to dynamic addresses, in which case I think that trying to use arptables to accomplish your goal would be tricky to say the least. But again, this is quite off-topic for this list... -Tom -- Tom Eastep \ The ultimate result of shielding men from the Shoreline, \ effects of folly is to fill the world with fools.
