I'm stuck..

I have 2 real servers, 1 LVS running ldirectord.
I am using wlc to schedule, w/ persistence.  I am using masq for routing
etc.

I want to add a third server and I'm having some problems.  Here is a
trace from the LVS (watto is my workstation)

from the client browser, no data is ever received (It does work if you
avoid the LVS).  I've checked my ipchains ruleset and I've checked the
tcpip config in /proc against a working web server, and everything looks
good to me.  Any suggestions where to go next ?  

btw:  the working server is running on RH 6.1, the new one is running on
RH 6.2.  I know there are some arping issues if you are using LVS-DR,
but I'm not.  I use MASQ.
