I am running into an issue with multiple zones on an M5000 with 2 NICs. The NICs are on separate VLANs. These zones are using the 2 NICs to communicate with other systems but when they need to communicate with a zone on the same system, but different NIC, the application fails. The network guys here indicate that no packets leave the origination NIC. And, when I run a traceroute from one zone (on NIC#1) to another zone (on NIC#2), the traceroute take 1 hop but never access the default gateway.
Here's some diag:
Here's the traceroute:
Notice the packets don't go through the default gateway.
This is a problem because the application on zone1 will not start due to a communication issue.
I'm trying to get the zone to send the packets to the default g/w so the app comes up.
Ping and traceroute are special on Solaris zones. Interaction between zones for ICMP packets is permitted.
Is there any way I can tell the zones "use the default gateway for all communication - don't communicate with the other zones internal to the global zone."
If you want zones to communicate through an external gateway, use exclusive IP zones, not shared IP ones. When using shared IP like you do, there is a single IP stack shared by all zones. That means there is no chance for a packet to leave the server if its destination address is local. This is by design and by standard.

Passing all traffic between two zones through a network device, such as a router, is not supported at this time since inter-zone traffic never reaches a network interface card.
I'll try setting one zone to exclusive IP and test.
The white paper you quote predates exclusive-ip zones so isn't very helpful. As an update to what I previously wrote, if you want to stay with shared-IP zones and are using a recent enough Solaris release, you might also use the defrouter zone configuration parameter to overcome the previously mentioned restriction. see Using zonecfg defrouter with shared-IP zones - What the krowteN? for details.
Hello Admins,
My ask is how can I add two different subnet IPs to same box with two different gateways?
The issue is I can connect to the box when I am on ethernet LAN, but I am not able to connect to the same IP when I am on wifi. The server is RHEL 7 VM on vmware.
How can I get connected... (4 Replies)

Hi all,
I'm having some trouble identifying what route is being used to talk to a target host. I can figure it out by looking at the routing tables but I want to automate this and don't much feel like scripting the network mask logic when I'd think there'd be a way to have the OS do it for me....

I am new in squid proxy.
My question is how to (and if it's necessary) to set one NIC for inbound traffic (http requests) and one NIC for outbound traffic (http answers)?
Thank you in advance! (4 Replies)

Hi,
I have a problem with a server disconnecting from the network.
