Does the load balancer have ICMP disabled? That'd certainly explain that, unless you were able to ping it before --
Since you have the load balancer between the router, I suspect it's a load balancer issue. You can see what's going on by running tshark/tcpdump on the interface, and see what's on the wire. If you can examine the traffic between the load balancer and the servers, you'll learn more :-) Justin On Jan 24, 2008 10:40 PM, Daren Tay <[EMAIL PROTECTED]> wrote: > Hi guys, > > anyone? > > Thanks, > Daren > > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Daren Tay > Sent: Wednesday, January 23, 2008 6:29 PM > To: Vyatta-users@mailman.vyatta.com > Subject: [Vyatta-users] Weird Routing problem on VC2 > > > Hi guys > > I have this queer problem. > > My setup with Vyatta is like this > > > Internet --- Firewall --- Vyatta Router --- Load Balancer ---- 03 x Web > Servers > | > | > staging server > > > As you can see, the router seats in front of the load balancer. > First... generally whenever I plug out the network cable from the router, > and insert it back later, everything will fail to route. > Its as if the route table cannot get the new info on its own..
