Have you enabled packet forwarding?
/etc/sysctl.conf check for ipv4_forwarding or something like that. Set it to 1
Hello All
I am not an expert in Networking and hence i am posting this here for
assistance.
I have a CentOS Box which has 2 NICs
My setup is as follows on the CentOS server.
My WAN IP is 192.168.6.142/24
My WAN Gateway is 192.168.6.1/24
My LAN IP is 10.10.20.1/24
My server is able to browse the internet well.
i have connected my laptop network port to the LAN port of the server.
Laptop IP is 10.10.20.12/24 and i have put gateway to be 10.10.20.1
I am able to reach the gateway ie 10.10.20.1 from the laptop,however i
cannot reach anything on the internet (e.g i am unable to ping 4.2.2.2 or
8.8.8.8) Basically i cannot go outside to the internet.
On the server,when i do a netstat -rn,i get the following output
[root@linuxlearn ~]# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.168.6.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
10.10.20.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
0.0.0.0 192.168.6.1 0.0.0.0 UG 0 0 0 eth1
[root@linuxlearn ~]#
I have not put a gateway on the LAN
As you can see,the default route is OK.
i would like to be able to access the Internet from my laptop.
My questions are?
1)- Is there any config i have not done well or misconfigured?
(My thinking is that my laptop should be able to go to the internet
because the routing appears OK,however i stand to be corrected.)
2)- Do i need to do any NATing somewhere?
Kindly give me your thoughts on this issue.
Regards
Cynthia
