OpenSUSE 12.3 two interfaces not communicating properly
This is a basic diagram of my current configuration.
http://ppl.ug/_wF6aBSFwa0/ My problem is I VPN in to the 10.x.x.x/24 network and try to VNC or SSH to the Linux server. The linux server has two ether ports. Eth0 96.x.x.x/24 Eth1 208.x.x.x/28 The route command shows Code:
Kernel IP routing table When I move the GW to the 208 nexthop on the router I can access the 208.x.x.x from outside it's subnet but not the 96.x.x.x address. How do I get the server working so it can respond outside it's subnet on both interfaces? The interface that is not on the same subnet as the GW can only communicate with devices on it's own subnet. Thanks for you help. |
You need add two static route entry for 96.x.x.x/24 and 208.x.x.x/28 network into router and then router will know how to route the traffic.
|
The router has directly connected interfaces to those subnets. It knows how to get to them.
|
Does the VPN tunnel know these two subnet?
|
Yes from the VPN I can access both subnets.
|
What's the issue you get if outside can access both subnets through VPN tunnel.?
|
I can only access one or the other I can't access both at the same time. Depending on the default gateway that is set I can only access the one that has the gateway on the same subnet.
|
That's my meaning, the VPN tunnel don't both subnet and doesn't route correctly.
|
From the VPN I can access other devices on both subnets. It's not a routing issue at the router.
|
1)Incoming direction, outside traffic can access both subnet through VPN tunnel.
2)Outgoing direction, both subnet can access outside through VPN tunnel. So far I still don't get your issue and don't see any problem. |
