Hi, thanks for your response. The problem is that I don't have any "real" router. I just have a linux box, with one ethernet interface, and one hdlc using a cyclades pc300 card. On Monday 03 July 2006 22:33, suse@911networks.com wrote:

Hi,

I have a problem in a customer which I was been working on all day with no progress...

This customer has one synchronous cyclades pc300 card, up and running directly with a public IP provided by the backbone. They also have a ethernet card configured as another public IP provided by an ISP.

The problem is that when I set the default gateway with the router where the synchronous card is connected, the interface where I have another public IP cannot be reached by outside connections.

Most likely, it's not true, they can reach it, but the packets do not know how to go back.

...

The same happens if I change the default gateway to the other router (the one of the second connection), and if I put both default gateways at the same time.

Does anyone has a clue on how to make this work? I don't want load balancing, or anything like that. I just want to have this two connections working.

This is not a server issue but a routing issue. There are various ways of dealing this is standard problem, but how will depend on the routers and their language.

Personally, I would:

1. Use a routing protocol: RIP, EIGRP, OSPF... 2. Create a virtual interface with HSRP

The routers will do the rest of the job.
