Hi Guys,
I have a DHCP server in a farm but I see it's not reachable for my
clients using lx4nat
Is this DHCP protocol not forwarded or doesit need a helper like on a switch ?
Any suggestions would be great.
Thanks,
This is indeed known, was also happening on ealier versions.

separate figure for the maximum
number of clients memorized in the farm which we have set to 8196. I just want
to make sure that these 2 settings haven’t been confused as there are certainly
not 4096 simultaneous connections occurring.

A question I have about te TCP connections that are removed. The

the status of this host remains Down. A restart of the cluster, so

What can cause this issue ?

As this is much more stabke now I'm also thinking that you can' t have
them on high mem used HyperVisors, Zen is quite sensible for it, is
this known ? No ballooning is set on these Zen VM's.
For the rest perfect en becoming better and better!

Maintenance means maintenance, you need to check your default master
to seems what is going on.
You didn't configure this yourself ?

What I can add to this comment is that one cluster was where i got an
error report from, my application does that when it cannot connect.
After this, as this can be compared with a ping/connect, it was able
to connect again.

So the ping is no solution in my case, anyway I think it should be build in.

Hi,
When I do a failover I still need to do

to make it all working well again, especially for my Farm IP's where

A low arp table is not advisable, but Gratuitous ARP which Zen should
do, doesn't work that well ?

It seems that SNAT it not able to work in transparent mode as it
actually should do, like DNAT but than without GW.
Or is it possible to run it in routing mode using SNAT ?

Hi,
This is a great solution for external/internal loadbalancing, but as
my switches need to be the default GW's and this LB-ing is internally
to MySQL I would like to have some other solution which gives the same
result.
Is this possible ?
Thanks again.

Hi All,
is it possible to use this loadbalancer in Transparent mode so the
server behind the Loadbalancer sees the IP of the connecting client
and not the IP/hostname of the loadbalancer ?
Would be great to know how if possible!
Thanks,
Matt
aster and I get the same messages again.
I'm on the latest version, DNS is OK, NTP is synced so this couln't be
a problem. The VHID number is not used on the network yet.
How can this be possible ?
