Hi, The adsl router is set to 10.0.0.2, offering via DHCP it's WAN IP address to the FreeBSD box. PPP half-bridge mode is something strange, but very useful anyway. So, the FreeBSD box gets a live internet IP from the router and since the router is on a different network, the logfiles fill with arp errors that 10.0.0.2 can't be arp'ed because it's not on the same network, blah, blah, blah. Read this to understand the setup of my networking: http://www.adslnation.com/phpapps/phpBB2/viewtopic.php?t=402&sid=7f658e15ff642da866cd437cc7f0b841 You see that I have to force the subnet mask to something other than the one that the adsl router uses, in order to get routing working at all. Strangely enough, this problem doesn't exist at all on linux. It's a FreeBSD peculiarity. Anyway, I wouldn't consider using linux for my firewall/gateway. BR, -- Mike Jackson
