Trying to lb SMTP through the Kemp in order to provide a load balanced solution for the copiers.
If I telnet in to the 2 Exchange boxes, no problem. Everything OK. Tarpitting was set to 00:00:05, but I have reduced this to 00:00:00 to troubleshoot.
When connecting to the Kemp VIP I get a connection error : refused.
If I disable the SMTP VIP then re-enable, it'll work for a short period of time, but always fails soon thereafter.
It worked perfectly for a few months but now nothing I set (NAT, persistence, test probes etc) works.
This VLM also load balances https 443 for Outlook etc, with NO PROBLEMS AT ALL : PERFECT.
Any ideas ?
Kemp Version :
VLM 200 v7.1-16
