Hello,
I am new to network routing and I need help configuring a linux box with
two ethernet cards. In this case it's a Linux RH 7.3 box, in a cabinet
that already has a couple of Windows servers. The Windows server routing
is below as an example.
The Linux box has an out-of-band interface at 10.130.36.38 and a public
eth at 62.50.8.84. I had to add a route for the private interface so I
could access its ports. However, since I did that, the Linux box cannot
access the internet. The incoming requests to 62.50.8.84 are fine, I can
hit the web service fine, but the net is not visible from the linux box.
I think it's just a matter of adding a route but am not sure how.
Interestingly enough I can ping the outside machines but cannot browse
over the net. I remember that this worked fine before I added the route
to the private interface, so it must be a routing problem and not some
other issue.
The Linux routing table:
