Sounds like a routing problem?
This was our RS TUN setup process:
# set up tunneling interface for load balancing
#
# Amend Tunnel Address as required
#
# /sbin/ifconfig tunl0 xxx.xxx.xxx.xxx netmask 255.255.255.255 broadcast
xxx.xxx.xxx.xxx up
# /sbin/route add -host xxx.xxx.xxx.xxx dev tunl0
#
/sbin/insmod ipip
/bin/echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/ifconfig tunl0 192.168.1.100 netmask 255.255.255.255 broadcast
192.168.1.100 up
/sbin/route add -host 192.168.1.100 dev tunl0
/bin/echo 1 > /proc/sys/net/ipv4/conf/all/hidden
/bin/echo 1 > /proc/sys/net/ipv4/conf/tunl0/hidden
Are you sure you followed all these steps?

Subject: iptun for http - not working - pls help I'm going mad!
Hello Everybody,
I'm going mad here with something I cannot figure out.
I'm trying to simply take 1 server I have and make an LVS using iptun to
another server, coz the servers are on different networks.
On both servers I have redhat 7.3 with re-compiled kernel 2.4.18 including
the pacthes needed, and also the hidden patch.
ipvsadm runs fine on both machines but I still cannot get what I need.
Here is what I did:
on director:
I have 2 nics, each one with 1 adsl line, so both nics have live internet
ips (pls note these ips are fixed ips, they never change)
I want to have 1 of the dsls to iptun to my real server, so I did the
following:
ipvsadm -A -t ip_eth0_director:80 -s wlc -p
ipvsadm -a -t ip_etho_director:80 -r ip_eth0_real -i -w 3
and for sure I did echo 1 > /proc/sys/net/ipv4/ip_forward
on real server:
modprobe ipip
ifconfig tunl0 0.0.0.0 up
ifconfig tunl0 ip_eth0_director netmask 255.255.255.255 broadcast
ip_eth0_director up
echo 1 > /proc/sys/net/ipv4/conf/all/hidden
echo 1 > /proc/sys/net/ipv4/conf/tunl0/hidden
I setup http.conf on real server to use the Virtual IP (pls note the virtual
ip is the ip on eth0 on my director)
http is not working.
I could see on tcpdump that the packets arriving on port80 on my director
are being redirect to the correct ip on the real server, but I still get no
sites working.
Pls pls pls help me figuring out what I'm missing here and how to make this
work.
Thanks everybody.
