Operating Systems Linux Lan card not reaching Gateway Post 302680037 by dextergenious on Wednesday 1st of August 2012 06:22:59 AM

Hi
fpmurphy,

Firstly they do not point to same problem . First problem was that my node on one subnet was unable to connect to its gateway. BTW it is resolved now . May be some stucking at the network switch point was there. As I rebooted, it got OK.

My second post was one subnet not connecting to other with all ip forwarding done at the linux box connecting these.As you gave reply to stop firewall, I did that. But same status.

I am only able to reach the first subnet's gateway from the node in second subnet but this also bu putting route at node itself which I did not want. I am not getting what is going wrong. All posts I read on internet say these simple steps to make subnets communicate and I am doing them all, but still both subnets are unable to communicate .

/etc/sysctl.conf , ip-forwading = 1
sysctl -p
/sys/proc/net/ipv4/ip-forward, = 1
Firewall disabled

(From linux box , I am able to connect to nodes of both subnets.)

172.16.18.3 (node s1) ----> 172.16.18.2,
192.168.10.2 <---- 192.168.10.3 (node s2)

node 192.168.10.3 donot communicate with 172.16.18.2 (and so 172.16.18.3)

Any more suggestions ?

Thanks in advance

Dexter
