My employer is convinced that it all works well on Linux and wants to switch back. We have a network with several Livingston portmaster and a cisco router as gateway. Most of the dial-up ip addresses are on the same class c network as the servers and therefore arp -a should give the ethernet address of the portmaster for an address that is in use. It does on machines without an ip-alias. It doesn't on machines with ip-aliases. If this is supposed to be like this can somebody please explain why? The routing problem is solved by running routed which adds the dial-up ip addresses if somebody dials in. Our Linux machine has about 50 ip aliases and arp works fine on it without need for routed. To make things worse routed sometimes removes the default route and doesn't want to add it again unless you restart it. It really shouldn't be necesary to run routed should it?
