two dsl connections, two routers, dual nics on linux box , want to run two websites

Post by Laitk » Mon, 21 Jun 2004 03:58:19



Hello,

I have two dsl connections, with one public ip on each. I have a linux
box with two nic cards.

xx.xx.xx.xx(WAN)---ROUTER(LAN23.123.45.110) ---- MYLINUX
(23.123.45.107) eth1
yy.yy.yy.yy(WAN)---ROUTER(LAN192.182.1.1)   ---- MYLINUX
(192.168.1.100) eth0

I have apache listening on both interfaces.

Problem:

1. How do I make the packets route back to the gateway from which they
originate.

Currently the gateway marked as "default" is able to serve content
from the apache. The other one cannot.

I tried adding static routes, but that didn't work.

Any help is appreciated.

Thanks

1. two routers (two wans) connecting to one lan using two nics.

Hello,
Let me try reposting this once more maybe I wasn't too clear in my
previous post.
I have a Linux RH7.3 server running ssh service. I want clients to log
in using ssh from two different Wans.

Wan1: Frame relay router (closed network with another frame relay
router)
Wan2:DSL router allowing clients to login from the internet.

The ip of the frame relay router is 192.168.100.254
The ip of the dsl router is 192.168.10.254

The fr relay is associated with eth0:192.168.100.10 defaultgw
192.168.100.254
The dsl is associated with eth1:192.168.10.10 defaultgw 192.168.10.254

Our GUI network configurator is not working due to bugzilla reports.
However it worked during the initial install and setup of these two
cards. But now we cannot access the tool.
We tried linuxconf but that only allows us one default gw to be
configured. Only one network works at a time.

Is it possible to have two default gateways (one per interface) and
have the box recognize and negotiate them both at the same time?
Which config files can I vi to achieve the desired result of two
gateways without using the gui tool?
If we are only allowed one default gateway per machine, how will the
box know
that the other router exists?
If static routes is the answer, then it is not clear to me how this
will work.
route -net add 192.168.10.0 255.255.255.0 eth1
Remember someone coming over the internet will have a private ip of
192.168.20.1 nat'ed through some pubic ip 68.1.1.10 for example trying
to ssh to
my public ip 68.1.10.20 conecting to my eth1:192.168.10.10.

Any suggestions?

Thanks guys.
