LDIR 430 - Have to ping real before virtual replies
I have a fairly simple setup that's really starting to frustrate me. 1 LDIR with two real servers and one virtual IP.
FW <-----> LDIR ETH 0 <-----> LDIR <----> LDIR ETH 1 <----> WWW1 & WWW2
In this configuration, if I generate zero IP traffic for a short period of time (60 seconds or so), I cannot connect via http to the VIP for WWW1 & WWW2. If I ping the real IP of one of the the servers, it begins to work and does so until I let it sit for a few minutes, when it starts to fail again. I have a feeling this has something to do with ARP but I'm not sure.
Any suggestions of where to start? Two things to note. WWW1 & WWW2 have two NICs, one going to the LDIR, the other going to a database server and NAS on a private network. Also, there are only hubs (no switches) in this config.
