How to route all incoming packets from one virtual interface?
Hello, I'm trying to route all packets arriving at a particular interface by entering the same interface
the virtual interface eth1: 2 and now everything is routed by default gw configured on eth1.
Code:
eth1 Link encap:Ethernet HWaddr 0a:0e:64:18:52:72
inet addr:192.168.10.15
eth1:2 Link encap:Ethernet HWaddr 0a:0e:64:18:52:72
inet addr:192.168.10.23
default gw
Code:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.10.0 * 255.255.255.0 U 0 0 0 eth1
default 192.168.10.254 0.0.0.0 UG 0 0 0 eth1
I want all incoming packets from 192.168.10.23 going out from the same interface.
Some help?

Hello,
I am currently trying to limit incoming UDP length 20 packets on a per IP basis to 5 a second using IPTables on a Linux machine (CentOS 5.2).
Basically, if an IP is sending more than 5 length 20 UDP packet a second to the local machine, I would like the machine to drop the excess... (1 Reply)

we have our... (1 Reply)

Hi,
I'm quite new to unix networking and ip tables. I'm running a debian (htpc) server with two NIC's; eth0 and wlan0.
I'm trying to set it up in a way that eth0 is the default interface for internet, but some processes should run through wlan0.
For example, I'm using eth0 for downloads... (2 Replies)
Hi folks,
I have a debian server running an Apache daemon on the eth0 interface. Now from time to time the server has to open an openvpn connection (tun0) to other networks to get some data from there. During this period the Apache is no longer reachable under it's IP address on eth0 because all... (6 Replies)

LEARN ABOUT NETBSD
route.conf
ROUTE.CONF(5) BSD File Formats Manual ROUTE.CONF(5)NAME
route.conf -- static routes config file
DESCRIPTION
The route.conf file is read by the staticroute rc.d script during system start-up and shutdown, and is intended for adding and removing
static routes.
FILE FORMAT
Lines starting with a hash ('#') are comments and ignored. Lines starting with a plus sign ('+') are run during start-up, while lines start-
ing with a minus sign ('-') are run during system shutdown. If a line starts with a '!', the rest of the line will get evaluated as a shell
script fragment. All other lines are passed to route(8). During start-up, they are passed behind a ``route add -'' command and during shut-
down behind a ``route delete -'' command.
FILES
/etc/route.conf The route.conf file resides in /etc.
/etc/rc.d/staticroute
rc.d(8) script that parses route.conf.
EXAMPLES
In this example, the interface for the desired routing changes is set, the IP address on that interface is determined, and a route is added
during startup, or deleted during system shutdown.
# Set interface and determine current IP address for added route.
!ifname=bnx0
!ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}')
net 10.10.1 -interface ${ipaddr}
In this example, IP forwarding is turned on during start-up, and a static route added for 192.168.2.0. During system shutdown, the route is
removed and IP forwarding turned off.
# Turn on/off IP forwarding.
+sysctl -w net.inet.ip.forwarding=1
-sysctl -w net.inet.ip.forwarding=0
net 192.168.2.0 -netmask 255.255.255.0 192.168.150.2
