I have a great problem configuring realservers using ipvs
DR with kernel 2.6.8 on a alpha workstation with debian
my configuration is this, servers have 2 nic
(hope you use monospace fonts :)
eth0 20.2 eth1 10.2 20.1
----- R1 --
| |
20.20 eth0 |20.1vip |
C ---------|---- V --| eth1 10.1
|20.4 |
| |
----- R2 -|
eth0 20.3 eth1 10.3 20.1
ipvs on V works perfectly redirection packets on 20.1 to
10.2 or 10.3 (with 20.20 as source address), but after
arriving to R1 or R2 nic the frame vanish
i mean that using tcpdump on R1 or R2 one can see a SYN
packet arriving on 10.2-3, but nothing is sent as ack,
realserver interfaces remain silent
there is no arp problem, R1 and R2 have ip_forward
enabled, routing on R1 and R3 is simply 20.x to eth0 and
10.x to eth1, I tried with TFTP, WWW and SSH services
having the same result, I tried also to put a nc -l on R1
and R2 and I saw nothing
some month ago I tried with ipvs TUN and had the same
problem
I red the howto on the website without finding a solution,
I will be glad if someone could point me to any
documentation about setting up realserver for that
topology
thank you in advance
