adress traffic to tap0

Hello, I have a problem of routing traffic on two virtual interfaces I have created on my machine (CentOs6)

By using tunctl I created two virtual interfaces tap1 and tap2

let s imagine I gave them two different address

tap1: 10.1.1.1 net 255.255.255.0

tap2: 10.1.2.1 net 255.255.255.0

I m receiving traffic on my real interface eth0: 192.168.1.23 net 255.255.255.0

I tried by using brctl and iptables to send some traffic to tap1 and others to tap2.. unfortunately i m not able to get how to do it.

An example of splitting may be.. let s send all the icmp packets to tap2 and the others on tap1. Is it possible somehow? Can you help me with some instructions?

Regards

NAME
vde_tunctl -- create and manage persistent TUN/TAP interfaces SYNOPSIS
vde_tunctl [-f tun-clone-device] [-u owner] [-t device-name] vde_tunctl [-f tun-clone-device] -d device-name DESCRIPTION
vde_tunctl allows the host sysadmin to preconfigure a TUN/TAP device for use by a particular user. That user may open and use the device, but may not change any aspects of the host side of the interface. vde_tunctl is a simple copy of tunctl done for practical purposes. USAGE
To create an interface for use by a particular user, invoke tunctl without the -d option: # vde_tunctl -u someuser Set 'tap0' persistent and owned by uid 500 Then, configure the interface as normal: # ifconfig tap0 192.168.0.254 up # route add -host 192.168.0.253 dev tap0 # bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp' # arp -Ds 192.168.0.253 eth0 pub To delete the interface, use the -d option: # vde_tunctl -d tap0 Set 'tap0' nonpersistent SEE ALSO
