Hi, I realise my question is not directly related to iptables, but since I noticed the 'problem' using iptables I hope it's ok to pose it here. My Linux box gets its outside IP (LinuxIP) from a DHCP server. The IP address has been the same from the beginning, so I guess some static mapping is done (I'm no expert in this matter :-). It is a dual-boot system, and when I reboot to MS-Windows, I get a different IP (WinIP) which is also always the same. After having set up iptables, I notice that the Linux box drops all lot of outside traffic (mostly MS broadcasts) with DST=[my WinIP] SRC=[some host]. It is _always_ the MS-Windows IP address that ends up in the FORWARD filter chain. Since I am just a simple client on the network, is there maybe some Proxy ARP gateway that keeps the two IP addresses mapped against my MAC? It's no big deal and I just drop the specific packets before they get logged, but I'm just curious... --Jordi ___________________________________________________________ALL-NEW Yahoo!
