I have a question because we are having some issues with new peplink balance 380 , we have already tried MTU 1400,1440,1500 - not solved
we just replaced the old Load balancer machine and incoming mail are working fine with that.
here’s the network setup:
internet - ISP - router - IPS appliance - Internet Public SW- Peplink - IPS appliance - Internet public SW - FW - Access switch ( left to right)
After we replace the old Load balance when we try to send an email it works fine but when receiving an email it take 20-30 minutes in just simple text attachment.
what might possible problem that occurs on the unit or settings or anything that we missed out?
Please walk us through what might cause the problem.
Thanks in advance.
