i am load balancing across the WAN( three different networks). i tried
NATing, but it din't worked, So i am Trying TUNLing.
i did following stuff.
*At Load balancer:-- i did following*
**
First i did ipforward to 1 in sysctl.cfg file and then
I added following stuff in the /etc/network/interfaces file
auto eth0:0
iface eth0:0 inet static
address 192.92.35.1
netmask 255.255.255.255
After that restarted the network. i am also able to ping my VIP.
ipvsadm -A -t 192.92.35.1:443 -s rr
ipvsadm -a -t 192.92.35.1:443 -r 91.111.211.57:443 -i
ipvsadm -a -t 192.92.35.1:443 -r 91.121.111.43:443 -i
*and at Real servers:-- i did following*
**
ifconfig tunl0 up 0.0.0.0
ifconfig tunl0 192.92.35.1 netmask 255.255.255.255 broadcast 192.92.35.1
echo "1" > /proc/sys/net/ipv4/conf/all/hidden
echo "1" > /proc/sys/net/ipv4/conf/tunl0/hidden
echo "1" > /proc/sys/net/ipv4/conf/all/arp_ignore
echo "2" > /proc/sys/net/ipv4/conf/all/arp_announce
echo "1" > /proc/sys/net/ipv4/conf/tunl0/arp_ignore
echo "2" > /proc/sys/net/ipv4/conf/tunl0/arp_announce
echo "0" > /proc/sys/net/ipv4/conf/tunl0/rp_filter
echo "1"> /proc/sys/net/ipv4/ip_forward
i remember once i tried this kind of configuration and it worked, but now,
strange to me, it is not working.
Ldirector is working fine and able to retrive the test.html file which i
have placed to test the real web servers.
May you tell me what i have done wrong or what else i should do.

Anil Sharma
