Linux as router
Hi,
I have two subnets (172.16.18.0, 192.168.10.0) and a RH linux box. I know linux can act as router, but specifically want to ask if this acts as a router without any route addition on all nodes of two subnets. I mean , I need Not to add anything at each of the subnet nodes (obviously gateway is there) but only add routes in the linux box. I have checked enabling ip forwarding in files /etc/syscntl.conf and /proc/sys/net/ipv4/ip_forward. But that donot make any difference . I am unable to ping the node of 2nd subnet with the node of 1st subnet. My linux box has two nic's with 172.16.18.2 and 192.168.10.2
172.16.18.3 (node s1) ----> 172.16.18.2, 192.168.10.2 <---- 192.168.10.3 (node s2)
Firstly, is it achievable that by only adding routes on linux box I can make two subnets communicate. If yes then what route I need to put on this. (I donot want to add any route on the subnet nodes except the subnet gateway - 172.16.18.2 and 192.168.10.2)
Thanks in advance ,
Dexter
