Accessing from Load Balancer with virtual IP-Address

[jacob.rief@xxxxxx]

Hi,
how can I configure the Load Balancer so that I can access
any service with the virtual IP from the Load Balancer itself.
If the Load Balancer is configured for example:
(eth0=195.96.23.250 eth1=172.16.0.1)
# ipvsadm -A -t 195.96.23.250:80 -s wlc
# ipvsadm -a -t 195.96.23.250:80 -r 172.16.0.10:80 -m
I can access the Real Server with
# lynx 172.16.0.10:80
but I can't with
# lynx 195.96.23.250:80
Alert!: Unable to connect to remote host.


Something else...
ipvsadm.c version1.1 should be patched,
I think there is a small bug in there. For example:
(eth0=195.96.23.250 eth1=172.16.0.1)
# ipvsadm -A -t 195.96.23.250:82 -s wlc
# ipvsadm -a -t 195.96.23.250:82 -r 172.16.0.10:80 -m

I can't delete this entry with
# ipvsadm -d -t 195.96.23.250:82 -r 172.16.0.10:80
setsockopt failed: No such file or directory
No such destination

However, if I create a rule with the same port, everything works fine
# ipvsadm -A -t 195.96.23.250:82 -s wlc
# ipvsadm -a -t 195.96.23.250:82 -r 172.16.0.10:82 -m
# ipvsadm -d -t 195.96.23.250:82 -r 172.16.0.10:82
everything works fine
This patch would solve the problem:
