Hello,
regarding the VLAN the best option would be, in my opinion, to directly act on the switch (if it is managed) and separate the LAN trunks.
The idea is to create a new LAN trunk and let the 2 server ports to be exclusively part of such trunk, and the port which the router is attached to, be *also* part of such trunk. In this way the flooding domain would be limited to the 2 servers and...

Hello Primiano.
First of all I'd like to say thank you for such great module.
We've been using it for a few days and now we have some questions :)
1. It is recommended to use VLAN to prevent the network from being flooded. What kind of VLAN should we use? Tagged or untagged?
2. Could you please give us some advise regarding the switch configuration? We have 2 servers that shares some...

It's absolutely strange, i checked the linux/netfilter_ipv4.h of 2.6.28-11 and it contains the NF_IP_PRE_ROUTING define.
Did you run
make defconfig && make prepare && make prepare scripts
under /usr/src/linux* sources?

I think so. I found this in my .config file which I had copied over from /boot/config-2.6.28-11-server:
CONFIG_NETFILTER=y
I'm running a stock ubuntu 9.0.4 server. It looks like NF_IP_PRE_ROUTING is defined in include/linux/netfilter_ipv4.h, but I don't know why lnlb isn't finding it.

Is Netfilter enabled in your kernel?.

I'm getting an error when compiling lnlb. Any ideas?
