HI !!! Recently we encountered a routing problem implementing a subnet connected via SLIP. One of the difficulties was we can't change the routing table of our router (W) connecting us to the INTERNET. One of our host (T) acted as a gateway. The expected dilemma here was the subnet's workstations could never access the INTERNET. From the subnet's workstations, they can send packets but they never come back because there is no route in our router (W) towards the subnet's workstations. After quite sometime we figured that routing in the IP level would not be feasible since we can't change the routing table of our router (W). Instead, we used arp available in our host (T) gateway, running Linux, to the subnet. We added an entry, arp -s <remote-addr> <ethernet-addr> netmask 255.255.255.240 pub That solved our problem. This is Linux arp. I tried out FreeBSD's arp and discovered that there is no 'netmask x.x.x.x' argument. I was wondering if our host (T) gateway was running FreeBSD instead of Linux. How would FreeBSD have solved our routing problem? -- jf
