Hello there! I
�m trying to configure a LAN router using linux with statics routes. The idea is to route between token ring an Fast-Ethernet subnets. My configuration is the following: 1 PC with two cards, one token ring card (IBM auto 16/4) and one fast ethernet (3com 3c905c). I installed Mandrake and loaded the corresponding modules without trouble. The card configuration is the following: route add 172.19.15.0 netmask 255.255.255.0 172.19.15.158 up (for eth0) route add 172.19.16.0 netmask 255.255.255.0 172.19.16.1 up (for tr0) I had also set: echo 1 > /proc/sys/net/ipv4/ip_forward The problem is that I can see from the ethernet subnet the token ring card of Linux, but only this card, not the rest of the machines under the token ring subnet, and viceversa, from token ring I receive an ICMP reply from the eth0 card of the Linux server but none of the machines under the ethernet subnet. Does it needs same parameter to make the internal routing between eth0 to tr0 and viceversa ?. Other problem is that when I configure the tr0 card, I try to set a mask of 255/24 but it doen�t take this parameter because when I check it whith ifconfig i get a mask of 255/16. Any idea ?, ..with eth0 I don�t have any problem related like this one. Thanks in advance for some help. Jorge Carminati.
