[nsp] Local Director

Hi,

I have two machines from the same VLAN and same subnet.

"Between" them it has a local director.

When from Host1 I telnet to Host2 on its real IP address, it works.

But when from Host1, I try to telnet to the virtual IP address of Host2, it failed.

In this second case, a tcpdump on Host2 shows:

Host1-- <SYN=X>--------------------> Host2
Host1<--<SYN=Y><ACK=X+1>-----Host2
Host1--<RST>-------------------------> Host2
Host1--<SYN=A>----------------------> Host2
Host1<--<SYN=B><ACK=A+1>------Host2
Host1<--<SYN=B><ACK=A+1>------Host2
Host1--<RST>-------------------------> Host2
Host1--<SYN=C>----------------------> Host2
....

Since using the virtual IP address of Host2 oblige the traffic from Host1 to use somehow the Local Director, I guess that my trouble is on this machine, but I don't know how to show this.

Any suggestion any welcome.

Thanks

Christophe
