We have a need correctly do the following. I have been all over the
net and up and down through the various support people. I have it
somewhat operational now, but could use some help making it fully
correct.
We have a need for a new 10.10.x.x network for an external vendor to
have access and manage a few servers on. They have provided us with a
vpn/firewall just for them. They also need all traffic they generate
to go back out through their gateway (they have provided a list in
CIDR format).
We have an existing 192.168.x.x network we use internally that these
same servers are also a part of.
I have multiple nics on all 3 rhel 3 servers (2 ES and 1 AS). I am
currently doing 1 nic on each box for each network.
I have connectivity currently for the vendor and our network but
routing is a mess. RHEL wants to use the 10.x network as the default
route.
I have setup numerous static routes setup so traffic for the vendor
to those addresses will go back out through 10.10.0.1 their router/
gateway/vpn device so they are happy. But, any traffic now
originating from the servers will also try to go through 10.x when I
really want that to route through 192.168.x.x router.
I have done many things with /etc/sysconfig/network-scripts/route-
eth0, /etc/sysconfig/network-scripts/route-eth1 and the /etc/
sysconfig/network files in addition to using the redhat-config-
network GUI tool, but haven't found the right combo to give me what I
want.
Any ideas on best practices for something like this? Basically,
static routes to certain CIDR addresses need to route through
10.x.x.x router while the default router should be the 192.x.x.x
router in RHEL. I guess I justr haven't played around with static
routing in a long while and am missing something. Any help appreciated.
