Hi folks.

First of all, sorry if this message reaches the mailinglist twice, I'm
having some issues with my mail account.

I have a director running on CentOS 5.2 ( which has the vs
functionality already compiled into the kernel, so I can perfectly load the
VS modules.

I'm trying to load balance two Apache servers here. This setup was perfectly
working (using direct routing), until I had to change the listen port of the
Apache servers, instead of port 80, it now uses port 81. As from what I've
read in the documentation, I cannot have the VIP port be specified as 80,
and have the RIP port specified as 81, while still using direct routing as
forwarding method. In order to get it working, the docs stated that I needed
to use masquerading. So far so good.

Problem: When I browse to the VIP I'm not being redirected to an Apache
server. I executed tcpdump on the real server to see if any HTTP packets
were coming in, but execpt from the directors "request" polls, there is
nothing arriving.

I also executed ipvsadm -Lc, but the returned list is empty.

I must admit that I did not read the whole documentation as it is humongous
and my setup was working before. I honestly hope it is just something
trivial that I overlooked and that somebody here would be so kind to point
that out.

Who would like to help me solve this?  I would really appreciate.
