Hi,
I've been testing the uplink balancing pretty heavily as it was a very exciting new feature!
Found another issue - thought it originally was a mail server issue as new server had been recently implemented but now isolated it to uplink balancing on ASG. Issue is as follows:
Incoming IMAP-SSL + SMTP-SSL came into ASG using Additional IP address on Interface {Eth4} - one of my WAN connections. DNAT redirected the traffic to the appropriate server.
When trying to connect, external device would start to connect to the server (connection showed as successful in ASG packet filter) but would then fail to connect - mail server would show that the connection had started but then failed.
Since I've been having a few other issues with the uplink, I turned off the uplink balancing - issue was resolved.
Some other incoming services that were DNAT'd in the same way had never been affected so I investigated to determine the difference - they were all using the IP address as defined on the Interface (i.e. primary IP address and not additional IP addresses).
Created a new DNAT for the primary IP address for the mail services and then gave the new IP address to some external devices that connect. Turned on uplink balancing, external devices connect OK.
Just as a note of caution, the thing that threw me off was that I could initially connect using the 'additional' IP address i.e. my original config but would then for some reason fail if you then tried to connect an hour or so later.
Can someone else validate this please?
Cheers,
Darren
