Making FORWARD_IPV4=YES permanent / DHCP multiple routers
.../net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o ${UPLINK} -j SNAT --to ${IP_NAT}
This works fine, however I want this permanent so I don't have to run
the script on startup. I have the firewall setup with SNAT fine, but
when I write the file /etc/sysconfig/network with the line
'FORWARD_IPV4=YES' it still doesn't enable the ip forwarding after boot?
cat /proc/sys/net/ipv4/ip_forward
0
So how do I do this?
Second,
In DHCP, you can specify multiple DNS servers:
option domain-name-servers 10.0.0.1, 10.0.0.2, 10.0.0.3;
can you also do this with routers?
option routers 10.0.0...

linux ip forwarding problem
...ping requests at
its eth0, but it never forwards them to its eth1. So is the reverse
direction.
The forwarding node is Redhat 7.2, kernel 2.4.7-10. The two end points are
FC3, 2.6.9-1.667smp.
What we have done to enable IP forwarding on the RH7.2 node are:
(1) In /etc/sysconfig/network, add "FORWARD_IPV4=yes"
(2) "echo 1 > /proc/sys/net/ipv4/ip_forward".
(3) Change "net.ipv4.ip_forward=1" in /etc/sysctl.conf.
(4)
"echo 0 > /proc/sys/net/ipv4/conf/eth0/rp_filter"
"echo 0 > /proc/sys/net/ipv4/conf/eth1/rp_filter"
(5) We tried "iptables -F&quo...

ip_forwarding
Hey all,
I'm trying to swap to CentOS and I have just about everything working
except ip_forwarding.
I have
FORWARD_IPV4="yes"
in my /etc/sysconfig/network file but /proc/sys/net/ipv4/ip_forward does
not = 1 (also tried to set it to ="true" and just =true).
All the firewall (iptable) rules are in place. Why won't ip_forward stay
enabled?
I'm using the latest DL of CentOS and all updated...

How to connect across the Internet
Hello All,
Well my Samba server is up and running good, but I am now needing to
be able to let some of my users connect to our server who is not
located on our local network.
Actually they are located some distance away and I would like to be
able to allow then to connect.
Has anyone had any success with this and how it might be done?
Best Regards,
Lonnie
