Problem DNS - with multiples gateway.

[clicerioneto]

I have 2 internet links with different providers, or have, different DNS for each link. When I active the traffic balance, I have problem with DNS. Because when the connection traffic by LINK A, o LINK A will use the LINK B Preferred DNS because the DNS of LINK B tops the list.

What would have some solution?

I had the same problem, not with ebox but with a dual wan device.  To get around it I use OPENDNS, that way it can go out either connection and no one complains.

Hope that helps,

Is the problem with your clients or your eBox?

If the problem is with your client machines, you can add a multigateway rule to route the dns traffic by the right router.

If it's with eBox I can tell you how to modify it to make it use the right router.

In this case I have 2 rules:

One rule for the GATEWAY "A" and other rule for the Gateway "B"

For example: I can create 2 objects

The Object "DNS A" contains the DNS of the gateway "A";
The Object "DNS B" contains the DNS of the gateway "B";

The rules would thus:

## RULE "GATEWAY A"

Protocol: UDP
INTERFACE: eth1
SOURCE: ANY
PORT: ----
DESTINATION: OBJECT "DNS A"
PORT: 53
GATEWAY: "GATEWAY A"

## RULE "GATEWAY B":

Protocol: UDP
INTERFACE: eth1
SOURCE: ANY
PORT: ----
DESTINATION: OBJECT "DNS B"
PORT: 53
GATEWAY: "GATEWAY B"

oK?
